[wp-hackers] Percona Server and WordPress

[Brian Layman]

"Drizzle is optimized for massively concurrent environments. If we have 
the choice of improving performance for 1024 simultaneous connections to 
the detriment of performance with only 64 connections, we will take that 
choice."

Interesting. Definitely not a drop in replacement and yet "forked from 
the (now defunct) MySQL 6.0 tree in 2008".

It's been interesting reading about MariaDB. I found this link 
http://vbtechsupport.com/657/ ( and http://vbtechsupport.com/606/ ) with 
performance comparisons for MySQL, MariaDB and Percona.


Also in the comments it stated:
"MariaDB 5.2.x’s Innodb storage engine uses Percona XtraDB’s version of 
InnoDB so MariaDB InnoDB = Percona XtraDB. Hence, the nice boost in 
performance for innodb storage engine for MariaDB 5.2.x"
