And Yasufumi. He got us started with his code, results and presentation at the user conference a few years back.

#11 — I learn a lot by reading XtraDB code. I also get many ideas from XtraDB. And finally, when I want to solve a problem different than XtraDB, I have something to compare it to.

@William – the comparisons in this article are between the built-in InnoDB and XtraDB. In general both the plugin and XtraDB are in a class of their own for both CPU and IO over the built-in InnoDB. For the InnoDB plugin, you can see a history of posts here:

Recent benchmarks are available via Dimitri’s blog:

Do note when reading benchmarks that a lot has changed in the last year (or even the last week!). We are still to publish a benchmark of plugin 1.0.4 ourselves.

I understand most of the points will make administrating *much* easier. I haven’t really seen much of a difference between xtradb and the innodb plugin for cpu or io scalability in your previous benchmarks. Did I miss that somewhere along the lines? I understand the theory behind why your changes should improve the situation, but in such a complex beast as mysql benchmarks really help.
