Rsync rather slow...

At the very most im only hitting an average of 40MB/s - 60MB/s. And this is rather slow and was hoping to be in the 100's.

Main server setup as the rsync client has a 2 disk stripe and the second server is the backup with rsync server and a 3 drive stripe... both totaling the same disk space of 6TB.

Both also have 3 gigabit nic cards connected to the same switch configured for link aggregation. So each server has a 3 gigabit link.. and yet my speeds are this slow..

I know my hard drives won't put out 3 gigabit speeds... but I know the single drives should be putting out close to 80 or 90MB/s by themselves and they aren't green drives.. they are regular 7200 rpm seagates.

I'm tracking my traffic through Status | Graph | Traffic graph

Anyone else running into slow transfers as well? I do wonder if there is something other than rsync that may be causing this but I can copy from a few computers and see the graph go up to 78MB/s

I have managed some tests downloading from the nas to 3 seperate desktops and was getting over 100MB/s
