:!: Unfortunately, due to lack of free time I (ivoras) can't keep up with this project. I'm still interested in doing it, but I'll have to rethink about how to do it efficiently.

This is a project to track performance of the %%FreeBSD%% operating system through time. More info pending.

The idea is to do it in several stages:

  * First stage: "Tweaking the toggles" - collect information on how commonly (and not so commonly) used toggles affect the performance. For example: 

    * INVARIANTS
    * WITNESS
    * SMP vs UP
    * vfs.read_max
    * malloc debugging
    * kern.sched.ipiwakeup.enabled
    * hyperthreading
    * timecounters
    * kern.smp.forward_signal_enabled
    * compiler flags

This should establish base performance numbers and expectations
