[Gluster-users] Poor performance for nfs client on windows than on linux

[Chiku]

Hello,

I'm testing glusterfs for windows client.
I created 2 servers for glusterfs (3.10.1 replication 2) on centos 7.3.

Right now, I just use default setting and my testing use case is alot 
small files in a folder.

nfs windows client is so poor performance than nfs linux client. Idon't 
understand. It should have same nfs linux performance.
I saw something wierd about network traffic. On windows client I saw 
more receive (9Mbps) traffic than send traffic (1Mpbs).

On nfs linux client, receive traffic is around 700Kbps.

Can someone have any idea what happen with nfs windows client?
I will try later some tunning tests.
