Chris Wolf is a research VP for Gatner's IT professionals service. While traveling through Europe, Chris decided to do some very basic tests of VMware's PC-over-IP (PCoIP) and Citrix's ICA/HDX protocols. Chris writes:
"Note that the purpose of [Chris's] experiment was not to conduct enterprise-scale benchmarking. Instead, [Chris] simply wanted to experience VMware View and Citrix XenDesktop while connecting from a variety of locations. My experiences are documented in the following posts:
- PCoIP vs. ICA/HDX: AT&T 3G from Newark Airport
- PCoIP vs. ICA/HDX: Munich, Germany to New Jersey, USA
- PCoIP vs. ICA/HDX: Gavle, Sweden to New Jersey, USA
- PCoIP vs. ICA/HDX: Oslo, Norway to New Jersey, USA
To summarize, [Chris] found that as latency increased beyond 200 ms, ICA/HDX had a decided advantage over PCoIP. Text entry and menu response with ICA/HDX was still good enough to keep me productive, while the PCoIP response hampered productivity. When latency was relatively low (e.g., under 120 ms) both protocols performed well enough to meet my expectations. At several locations (i.e., Newark Airport, Munich, and Copenhagen) both protocols were able to deliver a good user experience."
