April 20, 2012 By 5 Comments
We are running internally a lot of benchmarks on our recently announced Percona XtraDB Cluster, and I am going to publish these results soon. But before that I wanted to mention that proper benchmark of distributed system comes with a lot of challenges. I am saying that not to complain, but to make sure, if [...]
Introducing new type of benchmark
February 25, 2012 By 16 Comments
Traditionally the most benchmarks are focusing on throughput. We all get used to that, and in fact in our benchmarks, sysbench and tpcc-mysql, the final result is also represents the throughput (transactions per second in sysbench; NewOrder transactions Per Minute in tpcc-mysql). However, like Mark Callaghan mentioned in comments, response time is way more important [...]

Improved InnoDB fast index creation
November 6, 2011 By 4 Comments
One of the serious limitations in the fast index creation feature introduced in the InnoDB plugin is that it only works when indexes are explicitly created using ALTER TABLE or CREATE INDEX. Peter has already blogged about it before, here I’ll just briefly reiterate other cases that might benefit from that feature: when ALTER TABLE [...]

Benchmarking Galera replication overhead
October 13, 2011 By 12 Comments
When I mention Galera replication as in my previous post on this topic, the most popular question is how does it affect performance. Of course you may expect performance overhead, as in case with Galera replication we add some network roundtrip and certification process. How big is it ? In this post I am trying [...]
Percona Server 5.1 with Galera replication
July 14, 2011 By 2 Comments
As you may know I closely follow Galera replication development, and right now I am evaluating how it performs in our benchmarks. Of course my closest interest is Percona Server, so I made port of Galera from MySQL/InnoDB-plugin to Percona Server 5.1.57. Right now it is only in source code https://code.launchpad.net/~vadim-tk/percona-server/percona-galera-5.1.57, but it brings couple [...]
Product to try: MySQL/MariaDB-Galera 0.8
June 13, 2011 By 34 Comments
I wrote about Galera about 1.5 years ago: State of the art: Galera – synchronous replication for InnoDB. It was about the 0.7 release, which was more like a proof-of-concept release (though Galera’s developers may not agree with that ) with some serious limitations (like using mysqldump for node propagation). The Galera team heard my [...]
