Hi Amukher,
Even after upgrade to 3.7 small files transfer rate is slow.
Below is the volume info.
Volume Name: integvol1
Type: Replicate
Volume ID: 31793ba4-eeca-462a-a0cd-9adfb281225b
Status: Started
Number of Bricks: 1 x 2 = 2
Transport-type: tcp
Bricks:
Brick1: integ-gluster1:/srv/sdb2/brick4
Brick2: integ-gluster2:/srv/sdb2/brick4
Options Reconfigured:
server.event-threads: 30
client.event-threads: 30

I understand that for replication it would take some more time, but
here its taking more time.
Time taken for git clone in non gluster directory = 25 sec
Time taken for git clone in gluster directory = 14 minutes
Its a huge difference. Plz let me know any other tuning parameters need
to be done.
I have seen this before and it primarily seems to be related to the
readdir calls done by git clone.
Turning on these options might help to some extent:
gluster volume set <volname> performance.readdir-ahead on
gluster volume set <volname> cluster.readdir-optimize on
Please do let us know what you observe with these options enabled.
Regards,
Vijay
