Hello,
I have very bad performance with glusterFS 3.12.14 with small files especially when working with git repositories.
Here is my configuration :
3 nodes gluster (VMware guest v13 on vSphere 6.5 hosted by Gen8 blades attached to 3PAR SSD RAID5 LUNs), gluster volume type replica 3 with arbiter, SSL enabled, NFS disabled, heartbeat IP between both main nodes.
Trusted storage pool on Debian 9 x64
Client on Debian 8 x64 with native gluster client
Network bandwith verified with iperf between client and each storage node (~900Mb/s)
Disk bandwith verified with dd on each storage node (~90MB/s)

I made a test script that try several parameters but every test gives similar measures (except for performance.write-behind), ~30s average for a git clone that take only 3s on NAS volume.
