database performance
The backend unit tests provided a base on which we built more extensive database performance tests, covering many aspects of database performance using JDBC.
Part 0: Fair Setup
The setup is well documented so that these results can be reproduced.
Part 1: Java - Linux - Databases
This report compares many different aspects of databases on Linux via JDBC.
Part 2: FreeBSD - Linux - Solaris
This report compares the performance of these 3 mainstream operating systems when it comes to running various JDBC workloads against MySQL and PostgreSQL.
Part 3: Linux Kernels
Focusing exclusively on the differences of Linux kernels from 2.6.16 to 2.6.23-rc.
