Around month ago Facebook has announced the Linkbench benchmark that models the social graph OLTP workload.

We decided to run this benchmark for MySQL Server 5.5.30, 5.6.11 and Percona Server 5.5.30 and check how these servers [...]

The script assumes that you have running N EC2 instances (in the same availability zone) running RedHat [...]

MySQL Replication vs DRBD Battles
April 28, 2008 By 12 Comments
Well these days we see a lot of post for and against (more, more) using of MySQL and DRBD as a high availability practice.
