If you have the time, could you post results with freebsd mounting asynchronously (add async as an option in the fstab) and linux mounting synchronously (again, sync in fstab as an option) as I believe these to be the opposite of the defaults. I, for one, would appreciate those results. --=20 If I write a signature, my emails will appear more personalised.
