Almost one year ago, after a long co-development with the startup Teradici, VMware launched a software-only version of the remote desktop protocol PC over IP (PCoIP). PCoIP support has been introduced in View 4.0, side by side with support for Microsoft RDP, and it’s obviously still present in the new View 4.5.
Since then, customers interested in VDI have wondered if PCoIP is on par or superior to the Citrix High Definition eXperience (HDX) protocol, an extension of the ICA protocol, introduced with XenDesktop 3.0 in February 2009.
While a few benchmarks have been published about the topic, there’s a lack of real-world tests that can answer the simple question: how the experience will be for the average employee?
Chris Wolf, Vice President of Research at Gartner, just provided an answer: the two protocols are on par on LAN, while Citrix HDX performs better over WAN links with more than 200ms latency.
Wolf tested both XenDesktop 4.0 Service Pack 1 and VMware View 4.5, through a L2TP/IPsec VPN to connect from Europe to his facility in US.
