I believe one of the keys to over-clocking is to use a faster bus speed (ie, 75 or 83 MHz instead of 66 MHz) which would also skew the numbers from those that are not over-clocking. Since I'm the person who started this thread a couple of days/weeks ago with a simple question on why my system does 'make world' slower than the rest of the FBSD community with similar hardware, I would support a test like this. Even though I have been using FBSD for over 1 year as my primary OS, I still consider myself a 'Unix Novice' and therefore would benefit from the discussion a test like this would generate on this mailing list. As another thought, if we could all agree on the associated terms of this test, maybe someone could volunteer to write a new section for the handbook on how to fine-tune your system for optimal performance (depending on the purpose of your FBSD box). Although it sounds like most of the people participating in this discussion already know what they are doing, some newbies (like me) could greatly benefit from this. Unfortunately, due to time constraints with school (I'm full-time at CSUH), I can not volunteer for this task. - - burton - - --------------- Burton Sampley bsampley@best.com or bsampley@haywire.csuhayward.edu PGP key available at http://www.best.com/~bsampley/pgp.html -----BEGIN PGP SIGNATURE----- Version: 2.6.2 iQCVAwUBNHCBH3t2O8KJtMdBAQE4hgP/ZKyY4EjNQub8NIOTGzprhL7dYp8zI0oO SUWdg4usvFoxyw6v5dBoifKEaz3HX6I3hTWBoMwt1XjkSjX3cFUskbLdG+ceOXli 5WQ4SCA4wY/gOtMR04KYET5oRBpnPndHdxg3RXEHP3U39d09b0NoXhkgy7hL9vGT Je0r0FUYeDo= =hWhl -----END PGP SIGNATURE-----
