Slow Replication

This is obviously a lot faster than the 800kB/s I've been getting up till now.

Has anyone else used either the HP P212 or the P410 for Open-E? I've narrowed down my issues to the controller card.

After discussing this with Open-E support, it turned out to be two things.

- Replicaiton needed tweaking by Open-E via a remote support session.

- I needed to enable the cache on the physical disks in my RAID.
