Gavin,

Here is a quick summary.

This is a single machine it is running file, storage and director
daemon. The postgres database is on a separate machine. All services are
communicating via IP not the loopback. There does not seem to be any
difference in speed if I use loopback or IP.

This is a dual quad core xeon with 4Gig of mem

We have 8 SATA drives connected to a 3ware 9690SA-8I raid controller in
a Raid-6 configuration. Card has 512M RAM and a battery backup unit.

The issue I am running into is during a full backup I am getting around
9.5Meg/s vs. the 85Meg/s on a restore. You would think the raid array
would be able to read faster than it can write.

Is that 85MByte/sec across the network or from local backup to local
disk?

Do you mind if I ask what media you're using at each end (tapes or
disks,
sata/scsi/lto-X/....).  That sounds pretty quick to me.
