Quick notes:

* Upgrade time was about 30 min...... (still need to run mysql table upgrade script)
* 50 mailboxes, range in size from 2gig to 25gigs
* Server is a Dell Precision 380, 8gig ram, (2) Intel(R) Pentium(R) 4 CPU 3.73GHz
* before upgrade, average load was 5.xx, 4.xx, 2.xx, after upgrade load is now 0.88, 0.55, 0.55...

this is awesome....much better utilization of resources....

Great job Zimbra team...
