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.

Hi all：I do the following test：I create a glusterfs replica volume (replica count is 2 ) with two server node(server A and server B)， then mount the volume in client node，then， I shut down the network of server A node， in client node， I copy a dir（which has a lot of small files）， the dir size is 2.9GByte，when copy finish， I start the network of server A node， now， glusterfs self-heal-daemon start heal dir from server B to server A，in the end， I find the self-heal-daemon heal the dir use 40 minutes， It's too slow！ why？I find out related options with self-heal， as follow：cluster.self-heal-window-sizecluster.self-heal-readdir-sizecluster.background-self-heal-countI want to ask， modify the above options can improve the performance of heal dir？ if possible， please give a reasonable value about above options。thanks！
