I had a long talk with a friend of mine a few weeks ago that now
works at KTH (Stockholm, Sweden) about AFS, replication and long
running jobs (webservers etc).
One notable thing was that my replication takes AGES, whereas
theirs takes a matter of seconds (for roughly the same data).
I only have one AFS server (Sun Blade 1000, 2x750MHz Ultra III,
1Gb memory) with all the volumes on two software RAID5 (behind
a Symbios Logic 53c875 SCSI controller w/ two channels).
There are two AFS partitions (i.e. two RAID5 devices) - 'a' and
'b'. I've tried my best to split the disks evenly on both channels
to try to increase speed.
Doing a full replication of a volume that have roughly 1.3Gb data
takes me 76 minutes (all three steps below). This replication is
done from partition 'a' to partition 'b' on the same server.
I see that the replication is done in tree steps:
1. Cloning Takes about 8 minutes
2. Forwarding Takes about 60 minutes
3. Deleting release volume Takes about 8 minutes
With this, I get 288Kb/second. Seems _VERY_ (!!) slow... ?
Any ideas? Where should I start looking?
