:Ok, I've run some more tests. Basically you want to run NFSv3 under

Oh, let me be a bit more clear: Run 3 nfsiod's on the client. Run
4 nfsd's on the server. e.g. 'nfsiod -n 3' on the client and 'nfsd
The reason is due to the way NFSv3 issues writes. NFSv3 issues a

buffer around and does a later commit rpc to do the sync, presumably
