Hi,

I have still the problem, that running video over x2go (per vlc or mates default paroleplayer) is really slow and laggy. server: Fedora 22, core2duo, x86, 4.0.1.19 client: linaro, cubieboard, armhf, 4.0.5.0

• I have testet with another x86 computer as client with no change
• I have connected the server with the other x86 client directly to find out if the network has a problem, with no change
• I have tried iperf, but the speed of my gigabit lan is fast
• I have changed the graphiccard of my server (if that changes anything)

I have to admit, that my server is an old core2duo/computer, with old radeoncard, ssd and 6GB RAM, but I just want to connect a single user from another room inside my home. (and at max one physical user) Fedora 22 was set up on the server 2 months ago with a fresh install and a lot of packages like libreoffice, 2 browsers, ... . x2goserver was set up from the repos. Running videos directly on the computer is no problem. Are there any limitations or something I can check (logs, something I can try out) or are there any minimum system requirements?

Thanks, Harald

Hi,

Thanks for pointing this out. I had x2goserver 4.0.1.19 on fedora and 4.0.1.xx on my client, which seemed to be an old version. I assumed server and client-version belong together. I installed 4.0.5.0 (from ubuntu armhf repos) on the client but had the same difficulties, eventhough it was better and more fluent now. I'll see if I can find another x86 computer and try it from there. I think my client is the problem (or the armhf-packages not 100% the right one for cubieboard). I will need some days to identify the guilty part, I'll write her again.

Thanks for all the information, Harald

Hi,

I don't think, that the client is the problem, cause I tested also a second x86-fedora22-client with exactly the same result, so I expect the server is the problem. I've asked at fedoraforum cause of preemptive kernel and they say the standard is still preemptive.

With nomachine 4.0 video is much better (even if not 100%), but with nomachine I can't use virtual desktop for free.

Any other suggestion? Server requirements, ... ?

Hi,

I've got some more information: the kernel itself is not preemptiv, but there are some preemptiv settings set. But I used an alternative preemptive fedora kernel and found only small changes. What I found:

• In vlc I have to deactivate overlay-mode
• In Parole I have to set "No Xv" instead of "X11/XShm/Xv" in settings, videooutput.

Parole works better than vlc and is at around 1-2 updates per second, which is far better than every 10 second, but still not really watchable. Perhaps there is still some wrong setting on my computer (caching the video-pictures?) or my server is at it's limit ... Though there are still 3Gb (of 6Gb) free, CPU is working at 10-30%, ping is nearly all the time lower than 0.5ms.

Thanks so far, Are there any settings or players you prefer? Is a core2duo@2.13Ghz too slow as server, which impact is on the graphic card (though I have no problems locally)

Hi,

My server is still a core2duo, perhaps this is the problem? Anyone here with similar "low" hardwaresettings? I don't know what preemtive settings mean either I have to admit, I got that information from fedora side. And I tried a real preemtive kernel for fedora, but I don't see any differences (perhaps a very small improvement, but this might be my subjective view). As stated in my last mail ping are beyond 0.5ms, nearly every ping before, during and after playing video with a handful spikes not excedding 2-3ms.

Could it be my cpu, my graphic card on server side or my whole system? I don't think the client (cause I used another client) or the network (pings, network transfers ok) is the problem. But cpu is not over 20% too. I haven't configured anything in x2goserver, just standard. On my server nomachine is installed for testing if this matters (nomachine is faster than x2go, but not really fast). Are there any logs I can search. I even turned off selinux und firewall for testing but it had no impact, firewall shouldn't be the problem either, cause we go over ssh.

Ok I try to shorten my mails, since the information you are asking for is in my last mail (and in some mails before):

• ping: < 0.5ms (some peaks every some minutes at 2-3ms), before, during and after video
• iperf (600-700Mbit/s), measured with no load
• cpu of server at 15-20% while watching video
• memory: approx 3-4GB (of 6GB) used, swap all free

Could there be a caching problem, is vlc or parole the "wrong" videoplayer?

Thanks, Harald

2015-09-09 20:15 GMT+02:00 Robert Dinse <nanook@eskimo.com>:

 Herald, did you ever do the ping as I suggested while trying to watch

video to see if perhaps there are some bandwidth / latency issues?

 Another thing you might do is run a top on the server and watch the

load while you're playing video, from a command line do a free and make sure you're not swapping.

Hi,

I've got some more information: the kernel itself is not preemptiv, but there are some preemptiv settings set. But I used an alternative preemptive fedora kernel and found only small changes. What I found:

• In vlc I have to deactivate overlay-mode
• In Parole I have to set "No Xv" instead of "X11/XShm/Xv" in settings, videooutput.

Parole works better than vlc and is at around 1-2 updates per second, which is far better than every 10 second, but still not really watchable. Perhaps there is still some wrong setting on my computer (caching the video-pictures?) or my server is at it's limit ... Though there are still 3Gb (of 6Gb) free, CPU is working at 10-30%, ping is nearly all the time lower than 0.5ms.

Thanks so far, Are there any settings or players you prefer? Is a core2duo@2.13Ghz too slow as server, which impact is on the graphic card (though I have no problems locally)

 Do a uname -a on the box and see if it has PREEMPT in the result

string. If it does then it is and then I'd start looking at resource usage on the box or possibly network latency issues. Might do a ping from your client while watching a video and see if you get any network latency spikes.

Hi,

I don't think, that the client is the problem, cause I tested also a second x86-fedora22-client with exactly the same result, so I expect the server is the problem. I've asked at fedoraforum cause of preemptive kernel and they say the standard is still preemptive.

With nomachine 4.0 video is much better (even if not 100%), but with nomachine I can't use virtual desktop for free.

Any other suggestion? Server requirements, ... ?

Thanks, Harald

Hi,

Cause this mail is quite long - in short - problem solved (at least for this mailing list), I have still a small problem:

• Right mouse click doesn't work in my x2go session:
• Left click works, middle click, scroll wheel, even the additional buttons browser back and for are working, but not my ight, I always have to hit context-menu-key on keyboard which works. Can you give me a hint of whats going on and how to solve?
• I'm using the latest (4.0.5.0) client version, problem is also on 2 x86 computers (1 client, 1 server) with both fedora 22 set up.

Original - analysed and solved problem: I went back to an x86-Client with fedora22 on it: picture is not as good as if I'm sitting in front of my physical-pc

• on the server deinstalled nomachine, which I tried for testing --> seemed to give some speed-up
• used a preempt kernel -> no real change
• changed the ssh encrypting to blowfish-cbc, arcfour -> little change (as aes is performant on i7, but not older models)
• used kaffeine --> big speedup
• If I'm using vlc the timebar sometimes moves on, but the video doesn't change. I don't know what this causes, perhaps some caching or vlc tries to write a direct write on hardware components. Parole-player seems to do something similar. kaffeine runs smoth,

(since I'm compressing here with 16m-jpeg), but good enough.

So x2go-server seems to work at least it works so well, that I don't notice any real differences. So I tested with cubietruck (cubieboard 3.0, armhf, mali-GPU) as client once again:

• nomachine, ssh and kaffeine have also given some significant speedup. At least a video covering one third of the screen (at 1920x1080p) is running really well, fullscreen is still a little but jumping, not as bad as before, but clearly visible.

So my problem seemed to be a combination of slow server, "wrong" player, interfering package (nomachine) and a slow client. For now I'll try another linux image on client, perhaps the mali-GPU isn't supported right in my software or the x11 on the cleint is too old. Perhaps there is also a limit (I don't hope so) what cubieboard can do. But I think this will be a problem I'll better post in cubieboard forums.

Thanks for your support! Harald

 Just for kicks how about fire up kaffiene firefox on the server and try

a youtube video? For playing video locally on the server I usually use kaffeine. Since I haven't used vlc or parole, I can't speak for how they work.

Ok I try to shorten my mails, since the information you are asking for is in my last mail (and in some mails before):

• ping: < 0.5ms (some peaks every some minutes at 2-3ms), before, during and after video
• iperf (600-700Mbit/s), measured with no load
• cpu of server at 15-20% while watching video
• memory: approx 3-4GB (of 6GB) used, swap all free

Could there be a caching problem, is vlc or parole the "wrong" videoplayer?

Thanks, Harald

 Herald, did you ever do the ping as I suggested while trying to

watch video to see if perhaps there are some bandwidth / latency issues?

 Another thing you might do is run a top on the server and watch the

load while you're playing video, from a command line do a free and make sure you're not swapping.

Hi,

My server is still a core2duo, perhaps this is the problem? Anyone here with similar "low" hardwaresettings? I don't know what preemtive settings mean either I have to admit, I got that information from fedora side. And I tried a real preemtive kernel for fedora, but I don't see any differences (perhaps a very small improvement, but this might be my subjective view). As stated in my last mail ping are beyond 0.5ms, nearly every ping before, during and after playing video with a handful spikes not excedding 2-3ms.

Could it be my cpu, my graphic card on server side or my whole system? I don't think the client (cause I used another client) or the network (pings, network transfers ok) is the problem. But cpu is not over 20% too. I haven't configured anything in x2goserver, just standard. On my server nomachine is installed for testing if this matters (nomachine is faster than x2go, but not really fast). Are there any logs I can search. I even turned off selinux und firewall for testing but it had no impact, firewall shouldn't be the problem either, cause we go over ssh.

No idea right now...

Thanks, Harald

 I get real time video, server I7-2600 100mb/s backbone, client,

old MacPro-1 4CPU 4G of RAM running Ubuntu 15.04 with preemptive kernel on 15mb/s Comcast cable modem, server running Fedora 22 with a pre-emptive kernel, don't understand what "preemptive settings" mean, either kernel is built so that it can be preempted or not. I can get 30 frame/second video not 1/2 frames per second. And even with a non-preemptive kernel I only see occasional glitches not 1 frame every ten second, so you've got something still really broken. Did you try the ping I suggested?

Hi,

Because projects like x2go, nomachine, ... are saying that it works (video, nomachine even says for their products you can do CAD even if I doubt this) and you don't see real differences from sitting in front of your pc. I don't want to use it mainly for video, I can use my PS3 for this. But if I want to watch a short video, so why not and if I optimize settings (what I've done) for video (which needs bandwith and good speed), also the rest of using will be more fluent, so my thoughts. Don't misunderstand me, 1920x1080p is the native solution of my screen as most screens nowadays have, I don't think that other people here who said they are getting 30fps real time video are using 640x480 for connecting via x2go. And since transfer is compressed I know I won't get the same quality as fullhd through hdmi (which has far more bandwidth than gigabit lan) and my videos themself are far away from fullhd, at least most of them. So not the video is 1080p, but the screen resolution! But at least between two x86 pcs I now get a fullscreen video with kaffeine (+audio) which is quite fluent and quality is quite ok.

Cubieboard itself is sometimes a little bit slow and there is no "real" chrome (just chromium), and some other things. So I thought I'd just use it as a thin client for my main-pc (which is used by 2 persons incuding me) and I wanted to see if I can get it there where I don't notice any differences between sitting in front of my pc or siiting "remote" in the next room. My last test with two x86 pcs went quite well, I'll have to test a little more with my board. So problem here solve, video is playing.

But I've still the problem with my right mouse click, any ideas?

Thanks, Harald

Are you series? 1080p? You should really watch it in another way then X. The basic 1080P video size requires more then a specific amount of bandwidth. Why would you want to watch a 1080P video over X?

  Okay a bit more experimentation, with full screen 1080p video running,

as I mentioned I'm only getting around 15fps. 8Mbit/s bandwidth is used. Only about 14% CPU is used, 0.56 load on a 4 CPU machine, and there is 1GB of memory still free so not swapping on server.

  On the client about same CPU occupancy but most of that has nothing to

do with X2Go, it's other local stuff running. 2 GB still free so not swapping.

  So there is neither a CPU nor bandwidth nor memory constraint on either

server nor client.

  These are ping statistics:

--- fedora.eskimo.com ping statistics --- 19 packets transmitted, 19 received, 0% packet loss, time 18027ms rtt min/avg/max/mdev = 8.288/9.627/12.287/1.101 ms

  This is pinging from my workstation on a Comcast cable modem to my server

at the co-lo facility. As you can see no bad latency spikes, 12.2ms is max and that's pretty reasonable for a remote connection.

  So there has to be some software bottleneck involved.  Any suggestions at

other things to look at?

I tried just now x2go at 1080p full screen from Ubuntu 15.04 client to

Fedora 22 server and I am not getting full motion video, it is reduced to about 15 fps.

I am in the process of troubleshooting to try to determine where the

bottleneck, but something broke my server since I last logged in with mate and mate-settings-daemon is continuosly starting and dying so that probably isn't helping.

Once I get this resolved I'll try harder to narrow down where the 

bottleneck is occuring. It's NOT bandwith at 1080p is using about 8Mbit/s on a 25Mbit/s client connection and 100Mbit/s server connection and ping times are still good so not network latency issues.

Hi,

Because projects like x2go, nomachine, ... are saying that it works (video, nomachine even says for their products you can do CAD even if I doubt this) and you don't see real differences from sitting in front of your pc. I don't want to use it mainly for video, I can use my PS3 for this. But if I want to watch a short video, so why not and if I optimize settings (what I've done) for video (which needs bandwith and good speed), also the rest of using will be more fluent, so my thoughts. Don't misunderstand me, 1920x1080p is the native solution of my screen as most screens nowadays have, I don't think that other people here who said they are getting 30fps real time video are using 640x480 for connecting via x2go. And since transfer is compressed I know I won't get the same quality as fullhd through hdmi (which has far more bandwidth than gigabit lan) and my videos themself are far away from fullhd, at least most of them. So not the video is 1080p, but the screen resolution! But at least between two x86 pcs I now get a fullscreen video with kaffeine (+audio) which is quite fluent and quality is quite ok.

Cubieboard itself is sometimes a little bit slow and there is no "real" chrome (just chromium), and some other things. So I thought I'd just use it as a thin client for my main-pc (which is used by 2 persons incuding me) and I wanted to see if I can get it there where I don't notice any differences between sitting in front of my pc or siiting "remote" in the next room. My last test with two x86 pcs went quite well, I'll have to test a little more with my board. So problem here solve, video is playing.

But I've still the problem with my right mouse click, any ideas?

Thanks, Harald

So x2go-server seems to work at least it works so well, that I don't notice any real differences. So I tested with cubietruck (cubieboard 3.0, armhf, mali-GPU) as client once again:

• nomachine, ssh and kaffeine have also given some significant speedup. At least a video covering one third of the screen (at 1920x1080p) is running really well, fullscreen is still a little but jumping, not as bad as before, but clearly visible.

Are you series? 1080p? You should really watch it in another way then X. The basic 1080P video size requires more then a specific amount of bandwidth. Why would you want to watch a 1080P video over X?
