I continue to receive many questions from our customers on the expected performance gains of the new version of Hyper-Threading in Intel’s Core i7 processors. The answer requires a little bit of discussion on Hyper-Threading, a little bit on ESX, and comes with some performance data. If you are still interested, read on.

Four Things You Should Know About ESX 4’s Scheduler
[This is the last re-post of old community content. But this content is important enough to be worth a re-post.]
I spend a great deal of time answering customers’ questions about the scheduler. Never have so many questions been asked about such an abstruse component for which so little user influence is possible. But CPU scheduling is central to system performance, so VMware strives to provide as much information on the subject as possible. In this blog entry, I want to point out a few nuggets of information on the CPU scheduler. These four bullets answer 95% of the questions I get asked.

Newer Processors and Virtualization Performance
[New content has been added to this is an update to an old article from the performance community.]
Newer processors are much more important to virtualized environments than the non-virtualized counterpart. Generational improvements have not just increased the raw compute power, they have also reduced virtualization overheads. This blog entry will describe three key changes that have particularly impacted virtual performance.
