I was using nfs service on OpenBSD (amd64) since version 5.6. The whole setup process repeats the steps in official FAQ on the OpenBSD's homepage. The problem was and remains (now in version 5.9 amd64): in TCP mode the upload speed is about 20-30MB/s which is quite acceptable for my needs, but the download speed is about 32Kb/s.
As a workaround I had set up the debain client to connect to my NFS-server in UDP mode. In that mode the speed was good in both directions. In recent versions of debian OS the UDP option for NFS-client disappeared. The question is: is it possible to fix TCP mode in NFS server or is it still the problem of the NFS client?
