I am not seeing the performance you were. I am running on 500GB of data:
[root at gqas001 ~]# gluster v rebalance testvol status
Node Rebalanced-files
size scanned failures skipped status run
time in secs

Based on what I am seeing I expect this to take 2 days. Was you rebal run
on a pure dist volume? I am trying on 2x2 + 2 new bricks. Any idea why
mine is taking so long?
