Abstract

Citrix Systems, Inc. commissioned The Tolly Group to evaluate the performance of XenApp when it is virtualized and optimized by its XenServer virtualization solution.

Tolly Group engineers examined the maximum number of concurrent users a single XenApp server could support in a 64-bit virtualized server environment using XenServer. Engineers measured the performance of XenApp running on a physical 64-bit server and both 32-bit and 64-bit virtualized environments. The aim was to prove that virtualizing XenApp with XenServer does not degrade user scalability significantly compared to a native physical server environment.

Tests were conducted in April 2008.
