[X2Go-User] X2Go speed (Gb LAN) vs. pure X

[Robert Dinse]

      I am curious what desktop environment people having problems are using?
I use Mate pretty much exclusively so maybe it's an issue with a different
desktop, or maybe one of server resources, although my workstation is antique
my servers are modern i7-6700k systems maxed out on RAM (64GB).

      The only time I experience any issues if I stream 1024p media fullscreen,
and then it's only an occasional stutter.

      I am anxious to try the adaptive option but I am running vivid and the
repository for nightly builds is only for debian / jessie.  Is there a
repository for nightly builds for vivid vervit?

Most of my testing was done using Ubuntu as server (within VM - Parallels Desktop). But my customers have also tested in real and found 'adaptive' behaving better. IMHO worth trying at least.

For anything larger (Google Chrome being a serious offender, as it always updates the whole rendering area) it is much slower. Even just scrolling in Firefox is "laggy". Pure X is much faster for these large screen updates. I have tried various settings, 4k-jpeg is almost acceptable speed-wise but still not fast enough.
