Death match! EBS versus SSD price, performance, and QoS
February 21, 2011 By 55 Comments
Is it a good idea to deploy your database into the cloud? It depends. I have seen it work well many times, and cause trouble at other times. In this blog post I want to examine cloud-based I/O. I/O matters a lot when a) the database’s working set is bigger than the server’s memory, or [...]

November 24, 2008 By 17 Comments
Our customers or prospective customers often ask us how we do a performance audit (it’s our most popular service).

October 13, 2008 By 7 Comments
Percona’s patches are now available to a wider audience via OurDelta, a community effort to provide builds with features (Percona patches, Google patches, etc) and storage engines (PBXT, Sphinx, etc) that aren’t in the main MySQL server.
