I realized as I was writing today's VDIworks article that we never published the performance videos that we recorded last year when we visited Qumranet's (now Red Hat's) offices in the Bay Area. The information we got is very interesting, but publication was hung up when Red Hat acquired Qumranet, and the videos got lost in the shuffle.
The test methodology was pretty simple - we wanted to see how each protocol (SPICE, RDP, and ICA) performed in a controlled environment. We did this before we stress-tested the SolidICE and XenServer-based solutions, so this has nothing to do with server sizing or anything like that. This is a simple setup with one client talking to server running a single XP virtual machine. In each scenario, we ran through the same tests and recorded what the user actually sees as well as what the CPU utilization and network bandwidth metrics within PerfMon showed. Each of these scenarios can be viewed from within the player after it is launched:
- ICA Protocol - Business apps on one screen
- ICA Protocol - Business apps on four screens
- ICA Protocol - Multimedia apps on four screens
- RDP Protocol - Business apps on one screen
- RDP Protocol - Business apps on four screens
- RDP Protocol - Multimedia apps on four screens
- SPICE Protocol - Business apps on one screen
- SPICE Protocol - Business apps on four screens
- SPICE Protocol - Multimedia apps on four screens
To watch the videos, click here or on the screenshot below. During each scenario, you can click the Swap button under the small video to swap videos from small to large. It's especially useful in this case since you'll sometimes want to see the user experience in the big screen instead of staring at PerfMon for the entire segment.
