Hello, all. We are still trying to address the very poor performance of rdesktop sessions transmitted over NX - much slower than native RDP although we were expecting it to be much faster. In reading the NX documentation, we saw that they have a packing algorithm especially for RDP. However, whenever we enable this packing algorithm, the session aborts. Has anyone successfully used it? How do we troubleshoot this issue? Thanks - John
The actual pack methods support by libxcomp3 seem to be in this file:
http://code.x2go.org/gitweb?p=nxcomp.git;a=blob;f=Loop.cpp;h=76622d820f58e56...
Obviously, x2goclient (and pyhoca-gui) offer more pack methods than
currently supported.
@Alex: any clue on this??? We should remove the non-NX methods?
@John: I currently am logged in on from my Debsqueeze notebook to an
x2goserver in my office (LAN) that draws in 3 rdesktop session from
three machines via DSL (WAN, 3500bit/s). All three work very smoothly
while at the same time another host here draws backups from some
servers on the internet... I use 16m-png-jpeg-9 for that.
Cheers, Mike

Our performance is adequate for some things but major screen repaints are brutal, e.g., viewing large and dense architectural drawings in PDF files or scrolling through large graphics on poorly designed web sites. One of our favorite tests is to open notepad up full screen, type a full line, copy it, and hold down CTL-V. The first few pastes are fine but it becomes dismal as we get to the bottom of the screen. Performance is dramatically better in direct RDP or SPICE - John
