Optimizing MySQL and InnoDB on Solaris 10 for World's Largest Photo Blogging Community - Video

The video of one of my three sessions, "Optimizing MySQL and InnoDB on Solaris 10 for World's Largest Photo Blogging Community", presented at MySQL Conference & Expo 2008 has been uploaded by Sheeri. I am very thankful to her for doing all the hard work and making it available.

There are a few slides that were edited out of video because of reasons beyond my control. However, you should still be able to enjoy most of the video.

There is one point related to this video that I would like to make: Based on my particular experience I was leading to believe that Solaris 10 Kernel had the same issue as Linux Kernel related to swappiness and swapping where the kernel will start putting more importance on maintaining file system cache than the mysqld process. However, towards the end of the session, it was pointed out by a Sun engineer (thanks!) that there must be something else going on as UFS on Solaris 10 shouldn't depict this behavior and a process shouldn't swap in favor of maintaining file system cache. I am having this issue on 3 of my servers and I am currently working with Sun engineers to get to the bottom of the issue.
