This shouldn't be necessary in FreeBSD >= 6.2.

"100" is ok, I'm using this value on all virtual machines.

Is it possible to upgrade your ESX from 3.0.2 to 3.5x? If not, there is
another setting on the ESX side that helps with timing problems (FreeBSD
or Linux guests): change "Advanced Settings/Misc/Misc.Timer/MinHardPeriod"
from 400 to 100 (this is default on ESX 3.5x).
