Sorry for the dumb question. I am trying to develop a new filesystem based on NFS, which runs in a very fast network environment. I used the source code of NFS2, but noticed that NFS write is very slow. Even if I changed wsize to 8192, it still can only reach 1MB/s. I don't know why. Because the network is extremely fast (over 100MB/s), I don't think network is the only reason. Any other reason?
Is the NFS write synchronous? Does that means the NFS server will not return before the data is flushed to disk? Because nfsd_write will close the file every time, I will assume that the data will be flushed to disk before return. However, even if I change nfsd_write to stop closing file, the write speed is still very slow. Can someone give me some advice about this?
