I just noticed that there aren't any links to the documentation on the patches. There are now links to all of it from http://www.percona.com/percona-lab.html and the particular patch you're looking for is documented at http://www.percona.com/docs/wiki/patches:microslow_innodb You can download Percona's enhanced version of the server at the links above, too.

However i can't find any usefull documentation. I read through various articles at the performanceblog, i looked at the manuals of mentioned tools. Still i can't even figure how to enable, disable and configure all the nice features mentioned above. Is there some general documentation available describing how to use percona patches?
