I recently stumbled upon a post that Peter Zaitsev published back in 2007 titled “Innodb Performance Optimization Basics.” It’s a great post and reading it inspired me to examine what’s changed in the nearly six years that have followed in terms of MySQL, Percona Server – as well as in all of the other now-available […]

If you are terrified by the stability of the results in MySQL in my previous post, I am going to show what we can get with Percona Server. This is also to address the results presented there Benchmarking MariaDB-5.3.4
We are happy to see that Percona Server/XtraDB and XtraBackup are raising popularity and to keep excitement we want to have more features and more performance fixes! If you are experienced software engineer and feel strong enough to hack InnoDB/XtraDB code we invite you to join our development team to work on the following (but […]
Xaprb (Baron) recently blogged about how InnoDB performs a checkpoint , I thought it might be useful to explain another important mechanism that affects both response time and throughput – The transaction log.
We’ve had such a large number of signups to our Migrating MyISAM to InnoDB webinar, that we decided to hold one more before the year is out: December, 8th 9AM PST: Introduction to Percona Server, XtraDB and Xtrabackup.
How long it may take MySQL with Innodb tables to shut down ? It can be quite a while. In default configuration innodb_fast_shutdown=ON the main job Innodb has to do to complete shutdown is flushing dirty buffers. The number of dirty buffers in the buffer pool varies depending on innodb_max_dirty_pages_pct as well as workload and […]
While a scale-out solution has traditionally been popular for MySQL, it’s interesting to see what room we now have to scale up – cheap memory, fast storage, better power efficiency.Â There certainly are a lot of options now – I’ve been meeting about a customer/week using Fusion-IO cards.Â One interesting choice I’ve seen people make […]
To continue fun with FusionIO cards, I wanted to check how MySQL / InnoDB performs here. For benchmark I took MySQL 5.1.42 with built-in InnoDB, InnoDB-plugin 1.0.6, and XtraDB 1.0.6-9 ( InnoDB with Percona patches). As benchmark engine I used tpcc-mysql with 1000 warehouses ( which gives around 90GB of data + indexes) on my […]
As you see MySQL is doing great in InnoDB performance improvements, so we decided to concentrate more on additional InnoDB features, which will make difference. Beside ideas I put before http://www.percona.com/blog/2009/03/30/my-hot-list-for-next-innodb-features/ (and one of them – moving InnoDB tables between servers are currently under development), we have few mores: – Stick some InnoDB tables / […]
Today we announce release 1.0.2-3 of our XtraDB storage engine. Here is a list of enhancements: Move to MySQL 5.1.31 Scalability fix â€” ability to use several rollback segments Increasing the number of rseg may be helpful for CPU scale of write-intentional workloads. See benchmark results. Scalability fix â€” replaced page_hash mutex to page_hash read-write […]
