[Gluster-users] Poor performance of NFS client for large writes compared to native client
Hi, I was comparing GlusterFS native and NFS clients and I noticed, NFS client is significantly slower for large writes. I wrote about 200, 1GB files using a 1MB block sizes and NFS throughput was almost half of native client. Can anyone explain why is that?

That can contribute to additional latency and less throughput than the native client. -Vijay
