Optimizing MySQL Performance with ZFS

Average rating: ****.

This session focuses on ZFS performance with MySQL, and explores its suitability for deploying workloads based on MyISAM and InnoDB. ZFS performance relative to other file systems and the impact of ZFS compression on MySQL performance will also be examined. The ZFS Intent Log (ZIL) and the second level Adaptive Replacement Cache (L2ARC) benefit from low latencies, and benchmark results will be presented with the ZIL and L2ARC placed on SSDs. ZFS also obviates the need for the InnoDB doublewrite buffer, and the performance
benefits of disabling this buffer will be discussed. Finally, tuning tips and best practices will be outlined for achieving optimal MySQL performance with ZFS.

People have reported that the “play” link loads for 15-20 minutes before actually streaming the content; however, the download link works just fine. I apologize for any inconvenience.

Could have been less general ZFS advertising and more MySQL specific findings, but I’m happy to get any information—it’s been pretty sparse!
