Thin Clients, VDI and Linux integration from the front lines.... Raw and sometimes unedited notes based on my experiences with VMware, Thin Clients, Linux etc.

I use my "myCitrix" logon credentials on the Citrix Support page, here you can sign up for alerts to new Hotfixes and articles. Today on Sunday there have been over 120 released (I wonder whose job it is to release these on a Sunday?) although the vast majority of them have been for the Japanese versions, but the article below was worth wading through and deleting all the others.

Just as it says on the tin:

Makes very interesting reading on max users per server.
Based on these figures, it's *possible* that with real world Heavy Users (with Outlook/Notes and an Oracle App or two?) you still might be able to get 200 plus out of a Quad Opteron?

About 2 years ago I helped setup a large farm of 200 Blades, and in particular a Customer Services application that was mission critical and as a consequence it was throughly tested to breaking point with Mercury Load Runner. If you're not familiar with Load Runner - consider it the CSTK on steroids. Our experience at the time (early 2003) showed that BL20P G2's (equiv. DL360 G3) with 4Gb RAM and Dual 3.2 Ghz processors are capable of standing up to 80 - 90 Heavy Users before you start bouncing on the stops and impeading the users response time.  

That was based on Windows 2000 SP3 and XP FR2, and I'm confident that with Server 2003 and a couple of generations of Citrix later, as well as using the x64 versions that these test numbers are possible. What might have been more interesting is to see these same test results compared with a VMWare based OS as well?

Anyone have any other experiences?
