Percona Server is drop-in replacement for the popular MySQL, with full backward compatibility.
Percona Server provides diagnostic tools useful to DBAs, and more tunability of server behavior. Also included is Percona's online backup utility XtraBackup, the open source tool for the XtraDB / InnoDB.
Percona Server with XtraDB shows outstanding performance and scalability on today's high-end server systems with many CPUs and fast storage subsystems such as flash storage and SSD.
