Good morning,

 

We've a few dozen Wyse T50s on the Latest (U-1.041) firmware.

If a user tries to play video - for example on youtube.com, or bbc.co.uk (or even the smooth-scrolling animated background on the "Welcome to Firefox" page the first time firefox is launched) the session becomes unresponsive and sluggish.

This will be so unresponsive that it will appear the session is not receiving user input. It is receiving input but it's delayed by 5+ seconds. Anything displayed to the user will be updating at best a few times per second.

 

I've tested the same functionality on a Windows PC and on a considerably older Wyse R10L

In Windows performance was fine, so we were able to establish this is not an issue with the RD session Hosts.

On the R10L while performance wasn't perfect it was only a tiny bit sluggish, playback and screen updates didn't have dropped frames and there was no delay, however the user input was delayed by a fraction of a second which is probably to be expected on a low spec machine that is essentially updating a high quality image 30+ times per second.

Given this considerably older device with half the physical RAM (but admittedly lighter local OS) had very minimal issues, I can't see why the T50 has these issues unless there's a problem with the archaic versions of Ubuntu and RD Client on the T50s.

 

These issues persist even if the T50 is in Low Bandwidth mode, 15 bit colour and with compression turned on. I'm not convinced the compression tickbox actually does anything. I have also tried various potential fixes such as turning all experience options off except remote FX.

 

Does anybody have any advice on this?

 

Cheers
