My Challenge to Citrix’s Simon Crosby and VMware’s Stephen Herrod
In his blog post, Simon Crosby has a good point when he chastises VMware for using questionable methodologies in their own performance study, and for refusing to allow third party independent benchmarks to do performance comparisons. Simon presents the following graph in his blog post:
The graph above shows how end user response time rises for four environments as the number of concurrent users is increased (in this case a virtualized XenAPP server). VMware’s license restrictions prevent the identification of ESX as either Brand X or Brand Y, and I think Simon is absolutely correct when chastising Mr. Herrod about VMware’s policy of keeping the truth hidden in the shadows of obfuscation, instead of exposing it to the clarity of daylight.
