The test environment consists of two machines. They are called romulus and remus.
mythical tale of the foundation of Rome.
These two machines are to be as identical as possible except that romulus has the pH kernel-module, and remus doesn't. They are currently running a basic Debian GNU/Linux (potato) installation. Here is a more detailed description of both machines and there configuration.
This is the initial testing phase, where we intend to find out how different our two test-machines are. They are at this phase not under any extra load, and have been monitored in over sixty days doing "nothing". The monitoring is done by logging system-activity to a datafile, using this command:
date > vmstat.log ; vmstat 30 >> vmstat.log &After the logging-period, the files where copied from the machines, and parsed. The machines are now running a 2.2.19 kernel with the same configuration as the previous kernel except that one of them (romulus) has the pH patched kernel. PH is still inactive, and we should therefore get similar results to the previous test.
