From Jeff Buell at the performance team blog, VROOM!:
At VMworld last November I had the opportunity to talk to many ESX users and to discover for myself what performance issues were most on their minds. As it turned out, this endeavor was not very successful; everybody was generally happy with ESX performance. On the other hand the performance and best practice talks were among the most popular, indicating that users were very interested in learning new ways of getting the most out of ESX. VMworld was just the wrong audience to reach people who had concerns about performance. I was preaching to the choir, instead of the non-virtualized souls out there. At the same time aggresive marketing by other virtualization companies creates confusion about ESX performance. So it was decided that we needed to make a better effort at clearing misconceptions and providing real performance data, especially to enterprises just starting to consider their virtualization options.
