What version of gluster are you running on these?
I=E2=80=99ve seen high load during heals bounce my hosted engine around =
due to overall system load, but never pause anything else. Cent 7 combo =
storage/host systems, gluster 3.5.2.

I have run a pretty straightforward test. I created a two brick 50 G =
replica
volume with normal lvm bricks, and installed two servers, one =
centos 6.6 and one centos 7.0. I kicked off bonnie++ on both to =
generate some file system activity and then made the volume replica 3. =
I saw no issues on the servers. =20

Not clear if this is a sufficiently rigorous test and the Volume I =
have had
issues on is a 3TB volume with about 2TB used.
