[Gluster-users] Writing performance gets slower when write threads are many

Dear gluster users,

We have set up  glusterfs 3.4 on cent 6. 2 Gluster FS servers are
replicated each (2brick x 2).
Glusterfs is mounted on WAS as fuse.

We realized when there are more thread to write files on gluster fs, it
gets slower on writing.

We've set 250 thread to write 1M file each repeatedly. In this case we get
under 30 TPS. No NW bandwidth problem.
Is there any way to avoid performance degradation when there are lots of
write threads?

Look forward any help.
