Streaming and Virtual Hosted Desktop Study: Phase 2
Executive Overview
Intel IT conducted an internal technology evaluation to determine how using the most up-to-date hardware and software, such as Intel® Xeon® processor X5570 and Microsoft Windows 7*, affects server and network utilization as well as the performance of streamed and Virtual Hosted Desktop (VHD) compute models. This study followed a previous investigation, published in 2008, that compared streaming and VHD. Our current findings indicate that streaming provides better server loading and a more positive overall user experience with new Intel® Xeon® processors.
Major findings for Phase 2 include:
• For basic office productivity applications, systems based on dual-core processors with streaming provided a 26 percent better WorldBench 5* performance benchmark score than VHD.
• Streaming server utilization was consistently low. Streaming used about 1 percent of the processor while VHD used from 10 to 70 percent or more for up to 40 PCs.
• A richer graphical user interface (GUI) with more features in Microsoft Windows 7 contributed to higher cumulative network traffic for both streaming and VHD, up to a 57 percent increase in traffic for 20 users.
• Using WorldBench 5 tests as the primary indicator, local computing using the latest technology provided the best user experience.
Our findings indicate that increasingly complex user workloads make it challenging to measure, compare, and predict server loading. Beyond CPU usage, additional performance considerations now include the I/O subsystem and disk. New server optimization technologies, such as hyperthreading, increase performance but add to the complexity of tuning VHD environments. As user workloads evolve, optimization methods become more difficult and require constant attention.
