Hi folks

I have installed NFS but get bad performance.

      Copy 5MB from NFS Server (OpenVMS) to NFS Client (Linux)

real    0m19.284s

      Copy 5MB from NFS Client to NFS Server

real    0m2.193s

Doing the same with ftp:

ftp> get
5483813 bytes received in 0.69 seconds (7.8e+03 Kbytes/s)

ftp> put
5483813 bytes sent in 0.67 seconds (8e+03 Kbytes/s)

Putting the nodenames in each local hosttable did not improve.

Tried another VMS-server with the same result.

     First server is OpenVMS 8.3     and FTP V5.6 - ECO 3
Second server is OpenVMS 7.3-2 and FTP V5.4 - ECO 4
Linux client is Redhat

Occassionally I have had the same speed on NFS as on FTP,
but only on the first attempt. The consequent attempts were slow.
Now it is permanently slow.

 I don't think this is a tuning issue while copying one 5 Mb file.

  Any ideas?

Regards /Jan
