We’re having loads of performance issues with vDGA and server 2012 R2, any input will be greatly appreciated! Here’s a brief summary of our setup:
Dell R720 running VMware 5.1
Nvidia Grid K1 with GPU Passthrough in VMware (vGPU)
XenDesktop 7.1 App Edition
Server 2012 R2
Originally we had noticed that Server 2012 R2 was running slow in XD 7.1, so we hoped a K1 card would save the day!
We now log on to a XD 7.1 Citrix VM with a GPU attached and the performance is still not great, GPU-Z confirms that we are utilising the card, however everything is still so sluggish, even running a simple HTML5 benchmark (Fishbowl) runs terribly, utilising up to 100% CPU! At times everything feels extremely laggy!
We logged onto the same server via VNC protocol and couldn’t believe our eyes! The performance difference was staggering, the HTML5 test (Fishbowl) ran like a dream, utilising around 20% CPU at most! Everything was responsive just as we had expected it.
What’s confusing is that we can’t see the same performance when logging onto the same box via Citrix Receiver, is there a certain policy which we need to apply?
Or is this due to some sort of ICA limitation?
Any input at all would be greatly appreciated!
