A friend sent me a note telling me about the latest release of MySQL Clustering support that has been benchmarked at over 1 Billion queries per hour or 7.6 million rows retrieved per second! That is incredible performance. What is even more amazing is the fact that this is FREE open source software that you can download and install.
To my knowledge this is the first and only high performance relational database management system (RDBMS) available as open source. This new clustered release outperforms commercial databases costing as much as $20,000 per processor and not beginning to reach this level of performance.
What is significant here is that Oracle actually owns and controls MySQL but releases it through the standard open source GPL license. They also offer a commercial version of the product with full 24 x 7 support, but if you have access to the technical skills you can use the open source version.
Once again, open source is rivaling and exceeding features and benefits of commercial software.
