So this will be just a small teaser post about MySQL 5.6 upgrade.

We have been working on this for about a month and today was the day, when the first Percona Server 5.6 upgrade was done on the live environment. The bottom blue line shows up the performance of the upgraded host, and the other lines are the Good OldPercona 5.5 servers.

So here's a quick verdict: it seems that the MySQL 5.6 performs 25% better than the old 5.5 hosts. Great, isn't it?

I am still curious about the rest of the hosts.
