Improve LX/OS performance for ICA sessions

Hello Folks,

here are some settings that can improve the User experience for ICA sessions, mostly this is important for smaller devices like the old UD2 or UDC migrated old devices.

All settings can be found in system->registry, please test the settings one by one and not all at the same time! Use on your own risk! Test in advance!

General:

x.xserver0.backingstore: activate
x.xserver0.backingstorepolicy: WhenMapped

ICA related:

x.xserver0.backingstorepolicy
ica.wfclient.enableoss
ica.wfclient.twredundantimageitems (300 or 1000)
ica.wfclient.useserverredraw

Speedscreen:
ica.wfclient.speedscreenbacompressedcachesize: 1024 or 4096
ica.wfclient.speedscreenbacompressionenabled
ica.wfclient.speedscreenbadecompressedcachesize: 4096
ica.wfclient.speedscreenbamaximumcompressionlevel: low
ica.wfclient.speedscreenmmasecondstobuffer: 5

Please note: This might improve the user experience but it don’t have to be, depending on the user scenario/environment!

Cheers
Michael
