Description of problem:
Description of problem: We are doing a drive replacement test and have noted that the heal speed for disperse volume is very slow.
I replaced a 4TB drive with a different drive. It has been almost 26 hours since that. I see that only about 453 GB of data has been constructed back.
/dev/sdc 3.7T 3.7T 7.5G 100% /ws/disk1
/dev/sdd 3.7T 3.7T 7.5G 100% /ws/disk2
/dev/sde 3.7T 3.7T 7.6G 100% /ws/disk3
/dev/sdg 3.7T 453G 3.2T 13% /ws/disk5
Version-Release number of selected component (if applicable): glusterfs-3.8.4-18.el7rhgs.x86_64
Additional info: Volume is a distributed-disperse 2 x (4 + 2) = 12 volume, with the following options reconfigured:

Steps to Reproduce:
have tested replace brick for same data set for about 176GB data(on the brick being replaced) on a 2x(4+2) volume
On 3.3.1-async(126.96.36.199-8) the total time for replace brick to complete (ie heal completion) was 6hrs
on 3.4(188.8.131.52/11) was 4.5 hours
hence ie about 25% improvement.
hence moving the bug to verified
