Percona vs MariaDB vs MySQL in 2014

[Deebs]

So after all, what I said earlier did made sense.
@eva2000, when you are ready to benchmark, please hit me on Skype.

Basically MariaDB has MyISAM improvements but not XtraDB (they are usually 1 revision behind) but considering that Oracle want to convert the system databases to InnoDB sometime in 5.7 the performance improvement if any will be short.
