Percona Server Frequently Asked Questions
Percona Server is a backwards-compatible replacement for MySQL® that is much faster and more scalable, easier to monitor and tune, and has features to make operational tasks easier. It is designed to excel for cloud computing, support NoSQL access, and take full advantage of modern hardware such as SSD and Flash storage.
It is always free of charge and freely available for download. If you would like commercial support (recommended for production environments), it is available as part of our Percona Support offering.
How much faster is it?Much faster. Our 5.5 releases are much faster than MySQL 5.5. Performance of our 5.1 series is comparable to or better than MySQL 5.5. Performance of our 5.0 series is much better than MySQL 5.1. Percona Server with XtraDB can be more than an order of magnitude faster, as compared to the same version of standard MySQL. See benchmarks.

How is it different from standard MySQL?Percona's releases are based upon recent versions of the MySQL server source code. It is fully compatible with standard MySQL.
How is it related to other MySQL forks?Percona Server with XtraDB is the closest to the official MySQL Enterprise releases from Oracle. It is more conservative than MariaDB, which includes extra storage engines and more far-reaching code changes. (MariaDB is also built on the Percona XtraDB storage engine, but adds more changes to the rest of the MySQL server.) It is the basis for OurDelta, which is is essentially a redistributor of other forks.
When should I use Percona Server with XtraDB?Use it when you need more visibility into your server's activities, dramatically increased performance, and extra operational benefits, but you want to avoid risk from large-scale change. Use MariaDB instead when you also want more third-party storage engines and query optimizer enhancements.
Is there commercial support and maintenance?Yes. Percona stands behind Percona Server with XtraDB by providing 24×7 technical support.
