One of the most common questions from the field, especially after Citrix acquired XenSource, was “What type of performance do I get if XenApp is virtualized on the server?”. This Tolly Group Report conducts a performance evaluation of Citrix XenApp in a 64-bit virtualized server environment using Citrix XenServer Enterprise 4.1.0.  Test highlights include:

  • Achieves maximum performance of users when XenApp runs on a 64-bit XenServer virtual machine, operating with as little as 7.6% overhead versus running XenApp in a comparable physical server environment
  • Virtualized 64-bit XenApp exhibits 82% higher performance than a 32-bit virtualized environment using XenServer
  • Provide features to allow XenApp to run at optimal performance levels with default configuration
