Okay, I have 1 X100P and 4FXS modules (TDM400) and running zttool 
under normal load gets about 99.98.

I have 1 hard disk, no raid.

If however I run updatedb on another console I get drops down to 
33.508301, but still spends most of the time between 99 and 100.

I'll have to remember not to run updatedb during business hours 
(actually it's run from cron in the middle of the night anyway).

What other task would an asterisk system do that would use so much 
disk though?  Maybe recording every conversation on a fully loaded 
quad T1 box...
