Anyone running Citrix MPS 4.5 on VMWare ESX 3.5? We virtualised our entire infrastructure last year. The performance of the standard systems has been excellent (for instance, our SQL servers and Exchange 2007 systems run pretty much exactly as they did before). However the Citrix servers are very hit-and-miss - slow logons, application hangs, systems freezing, etc., runs poorly when more than seven or eight users logged on to each server. I have just taken a subset of our users and put them back onto a physical Citrix server, and straight away the performance is instantly better, the logon time is considerably faster to start with.
Admittedly we aren't expecting our virtualised systems to perform as well as a dedicated physical system, but the performance degradation appears to be hugely magnified with regards to the Citrix systems. Is anyone else running Citrix farms on ESX, and if so, are they experiencing similar performance issues, and how are they getting around them?
