[Gluster-users] glusterfs replica volume self heal dir very slow！！why？

[Roman]

Hi,

consider looking at this topic
http://supercolony.gluster.org/pipermail/gluster-users/2014-September/018577.html
. This guy made lots of test. It seems like 50 MB/s (or around 400 Mbps) is
the theoretical maximal limit for replica 1. I am waiting for comments to
this too.
