What sort of rates are you all getting for replication?
At 2.3.7 for a manual sync_client for a user, I'm seeing ~35MB/minute
across a 100M net to a linux SW RAID 1 pair of U320 disks.
Is this speed typical or abysmal?
Disks appear to be holding me back:
Device: rrqm/s wrqm/s r/s w/s rsec/s wsec/s rkB/s wkB/
s avgrq-sz avgqu-sz await svctm %util
dm-0 0.00 0.00 0.00 429.96 0.00 3439.65 0.00
1719.83 8.00 7.24 16.75 1.86 80.01
Production (40,000+ users) would probably be FC and gigE...
