Percona Server

MySQL replacement : Percona Server Percona Server is an enhanced, drop-in MySQL®  replacement which has been downloaded more than 1,400,000 times. 

Version 5.6 is the current major release. Review the latest performance benchmarks.

Percona Server is optimized for cloud computing, NoSQL access, and modern hardware such as SSD and Flash storage. With Percona Server:

  • Queries will run faster and more consistently
  • You can consolidate servers on powerful hardware
  • Sharding is delayed or avoided entirely
  • You can save money on hosting fees and power
  • You can spend less time tuning and administering
  • You can achieve higher uptime
  • Troubleshooting does not require guesswork

Percona Server is a free, open source MySQL alternative which offers breakthrough performance, scalability, features, and instrumentation. Self-tuning algorithms and support for extremely high-performance hardware make it the clear choice for organizations that demand excellent performance and reliability from their MySQL database server.

Percona Server 5.5 Benchmark

Percona Server's performance is exceptional. Not only is it faster, but as you can see in the benchmark at the left, it is more stable and consistent. Our research into server internals and our Six-Sigma-like focus on quality of service have resulted in the industry's most predictable response times and throughput. Standard MySQL suffers from complete lockups due to checkpointing and furious flushing to disk.


Vertical scalability and server consolidation is a reality with Percona Server. A few years ago, MySQL could not scale past 4 CPU cores, and had a hard-coded limit of 100 disk operations per second. Today, Percona Server scales to over 48 CPU cores—more than most commodity servers. And it can achieve hundreds of thousands of I/O operations per second on high-end solid-state hardware.

Percona Server excels in use cases where MySQL was formerly ill-suited. Here's a sampling:

Percona Server is designed for scientific performance optimization. The secret to its performance and stability is our years of work adding more measurability to the server. This has enabled thousands of users to find and eliminate causes of performance problems, quickly and reliably. Here are a few key ways Percona Server is the most measurable MySQL server you can get:

  • Detailed query logging with per-query statistics about locking, I/O, and query plan.
  • Performance and access counters per-table, per-index, per-user, and per-host.
  • Aggregated response time statistics for measuring performance, not just operation counts.
