Dave Brodin:
Thank you very much for the info. I'm really filling in because our
main system administrator's last day is tomorrow, unfortunately. I
guess it's 8.2-PRERELEASE (not sure how happy I am to find that out).
We did try 2.4.10 and it had the same problem.
I would bet that the problem is not that Postfix is broken, but
rather, that you have a problem with the way FreeBSD talks to your
hardware.
Dave, does the old server have multiple high rpm SCSI or SAS disks in a RAID
setup, but the new system has fewer, larger, lower rpm sata disks, possibly
without raid striping at all? A substantial drop in storage subsystem IOPS
throughput could be a possibility here as well.
I'll have to check tomorrow, but I'm almost positive they are all 15K
RPM SCSI drives. In both servers, they are external Dell PowerVault
storage units.
But I'm going to dig into the drivers and hardware to see what I can
find there.
