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

[Łukasz Czerpak]

Hi,

Have you tried 'adaptive' method with image compression set to ~7? Stable versions of X2Go client may not support this yet, so you'd need to use Nightly Builds.
It improved user experience significantly - none of other methods worked so smoothly.

Best regards,
Łukasz

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.
