We have a Percona 5.0 server installation in one of our product that I’m thinking of finally upgrading to something more modern.
I wanted to know if there’s a currently “recommended” version to upgrade to? It looks like the Percona 5.1 branch has a lot of active development on it even with the release of 5.5. Is 5.5 ready for prime time or is 5.1 still the safer/better upgrade?
Thanks!

I recommend 5.5. See [http://www.mysqlperformanceblog.com/2011/08/15/whats-the-rec](http://www.mysqlperformanceblog.com/2011/08/15/whats-the-rec) ommended-mysql-version/

Thanks Baron. That’s a great answer.
