Percona Server version 5.1.55-12.6 is now available for download. It is now the current stable release version.
It’s finally here! Percona Server Percona Server 5.5.8-20.0 is now available for download. This is a beta release of Percona’s enhancements to the MySQL 5.5.8 server. Here are some highlights:
In addition to building on MySQL 5.5, here are the changes we’ve made from previous Percona Server releases:
Percona Server version 5.1.54-12.5 is now available for download. It is now the current stable release version.
Percona Server version 5.1.53-12.4 is now available for download. It is now the current stable release version.
This is to follow up on my previous post and show the results for MySQL 5.5.8 and Percona Server on the fastest hardware I have in our lab: a Cisco UCS C250 server with 384GB of RAM, powered by a Virident tachIOn 400GB SLC card.
To see different I/O patterns, I used different innodb_buffer_pool_size settings: 13G, 52G, an 144G on a tpcc-mysql workload with 1000W (around 100GB of data). This combination of buffer pool sizes gives us different data/memory ratios (for 13G - an I/O intensive workload, for 52G - half of the data fits into the buffer pool, for 144G -[Read more...]
As we can see, MySQL 5.5.8 comes with great improvements and scalability fixes. Adding up all the new features, you have a great release. However, there is one area I want to touch on in this post. At Percona, we consider it important not only to have the best peak performance, but also stable and predictable performance. I refer you to Peter's post, Performance Optimization and Six Sigma.
In Percona Server (and actually even before that, in percona-patches builds for 5.0), we added adaptive checkpoint algorithms, and later the InnoDB-plugin included an implementation of "adaptive flushing". This post shows the differences between them and MySQL.
The post also answers the question of whether we are going to have releases of Percona[Read more...]

What is so special about it:
(While in Europe, we'd love to speak at your meetup group on Percona Server and/or MySQL Optimization. If you're a meetup organizer in London or Paris, please feel free to get in touch.)
