OWB Performance measurement
Introduction
This page describes how to benchmark OWB performance. Of course, that is not an universal method. It is just a method. So it probably have some drawbacks and/or some lacks.
The first part will describes tools used to benchmark performance like memory consumption or CPU load.
The following section describes the procedure used to measure performance.
Finally the last part reports on results.
Benchmark tools

Memory
mem_usage
A very interesting script is mem_usage which is a perl script which can be found here. This script take advantage of linux /proc/<PID>/maps file to compute some values like mapped executable size or data size.
Linux /proc interface
Many informations about running processes can be retrieved through /proc/ filesystem. In many situation the problem is to know which file to look at and how information are formatted in the file.
CPU
To be done.
