Awesome work on nfs-rdma in the later kernels! I had been having panic problems for awhile and now things appear to be quite reliable.
Now that things are more reliable, I would like to help work on speed issues. On this same hardware with SMB Direct and the standard storage review 8k 70/30 test, I get combined read & write performance of around 2.5GB/sec. With nfs-rdma it is pushing about 850MB/sec. This is simply an unacceptable difference. I'm using the standard settings -- connected mode, 65520 byte MTU, nfs-server-side "async", lots of nfsd's, and nfsver=3 with large buffers. Does anyone have any tuning suggestions and/or places to start looking for bottlenecks?
