If you think of it, what happens in the background is that the 1GB file is written not only from you to one of the servers, but also from this server to the other servers, so it gets properly replicated/distributed. So depending on your setup, you are not writing 1GB file once, but 3-4 times, hence the drop in speed. You could squeeze a bit more out of it if you can create the volumes over the servers' secondary nic so servers-to-server traffic goes through there. -- Sent from the Delta quadrant using Borg technology!
