Windows 7 IOPS for VDI: Deep Dive

Came across this thorough analysis of Windows 7 IO behavior put together by Jim Moyle.

The document named “Windows 7 IOPS for VDI: Deep Dive” cover many Windows 7 IO aspects with specifics for VDI sizing and deployments. The paper yet explains how to measure IO at the guest OS, hypervizor and application layers, including antivirus.

At the end you will find that the document is biased and tries to push a given product. However the quality of the paper is not overshadowed by that.

It’s a Good Read…

    Great article. We’re about to embark on the great Windows 7 journey. The table on page 7 is good but says it’s from Citrix. Is there anything similar from VMware specifically considering esx 4.1? Any thoughts on where 64-bit / 32-bit W7 fits into this analysis?

    I have previously compared Windows XP 32b and 64b; however that may be different from Windows 7. If you are interested read “Windows XP x64 in virtual environments might go beyond appearances” at

    From a brokering perspective there are no differences between 32 and 63 bit GuestOS architecture. From a hypervizor standpoint I wouldn’t be able to compare XenDesktop and vSphere, however vSphere has overtime proven to be a little bit more memory efficient.
