Website performance over RDP
I have been looking at an issue with Prit (fellow community member) at an issue that is cropping up. If you visit http://www.york.ac.uk/www.york.ac.uk you will notice there is a sliding picture set on the home page, this is controlled by java script I believe. If you connect to a virtual desktop and access this website with task manager open you'll notice that as the pictures change the CPU spikes. This isn't anything unique to EOP I have also noticed that native RDP does this and I also see simialr behaviour on my laptop when running Internet Explorer locally. When running locally the CPU doesn't spike as much but then you are comparing a laptop against a virtual desktop so its certainly not apples for apples.
Has anyone else seen this issue, any thoughts on improving it besides assigning more resource to the Virtual Desktop?

thanks Matt,
minor correction , website is www.york.ac.uk
also if you look at taskmanager - you get cpu and network spike as the image changes
local lan network vdi access is fine..but remote access via broadband affects vdi performance , when you goto this site, you get horrible browser lag

I am connected to this via IE6 from 2003 R2 Terminal Services in a seamless window and it works fine. Nothing noticable in task manager. This is using vWorkspace 7.2 MR1 from a client that is 2008 R2 SP1.

Patrick,
did you had this experience with Max-IT enabled or disabled on the TS? ... or doesn't it make any differences regarding the peaks?
In my opinion also the latency that you have to your session at the moment the picture slides tip the scales.
Actually i access our german vWorkspace farm from Yantai, China, where i am able to work fine from with our standard applications and a latency of 350 to 970ms (full desktop with EOP Xtream and graphics acceleration enabled for IE8 and Outlook 2k3).
When the picture slides i have a lag of about 3 seconds as long as my latency isn't more than 500ms, but as soon as it is more i am thanksful as soon as i was able to close this IE8 window again...
Holger
p/s: Max-IT is fully enabled in our configuration (w2k3 R2 wts).
