Wow! Russell, do you know of any Linux I/O and hard disk performance guides? I've recently read Adrian Likins' system tuning page [1] and am interested too see if there's anything more specific. Thanks for bonnie++ btw, - Jeff [1] http://people.redhat.com/alikins/system_tuning.html -- o/~ we all live in a yellow subroutine o/~ - auspex
