Subject: [Gluster-users] Writing performance gets slower when write threadsare 
many

Dear gluster users,

We have set upĀ  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?

That depends on a lot of factors - what interconnect are you using? 1GE? 10GE? 
RDMA? What are your bricks built on? SATA? SSD? RAID?

My first guess would be that interconnect latency and a kernel maximum for some 
connection count could be the problem.


Look forward any help.
Thanks.

Regards,
Youngseok jung
