NFS vs CIFS speed

It is really convenient to have an NFS exported file system from the DNS-323 when used as a backup repository for some Linux machine.

However I found it strange that the NFS user space daemon has rather sluggish performance- while CIFS (Samba) would process a write stream at 20 MBytes/sec the NFS barely reaches 5 MB/sec.

Is anybody here using the NFS and are you getting simillar results? Strangely enough the CPU load when copying data through NFS is below 10% so I suppose it might be a configuration issue?

I will dig around on the Internet for configuration tweaks but am clueless at this moment.

Re: NFS vs CIFS speed

Well I have made some moderate progress by increasing rsize and wsize to 32768 the speed went up to 10MBytes/sec

I guess that further progress can be made only with the kernel space daemon, rpc.nfsd. It is a part of fun_plug but does not run on DNS-323 so I gather it was never ported to our platform?
