Samba consumes a lot of resources

Agreed. This is a good time: it is about as fast as ViewNow NFS client
with MultiNet NFS server. Your observations about the relative speed of
the DEC 3000 Model 600 are correct and relevant. I was not overly
concerned about that; I am much more concerned about the smbd process that
went wild and consumed all those resources.

The improvements in Samba performance are noted and appreciated. Merci
Jean-Yves and others.

I suspect that MS Windows will create and then rename a file. Samba seems
to have a problem with that. But I am speculating.

I copied a file (C source code) from the VMS system to the PC and was able
to edit it with GVIM. I could not copy it back to the VMS system: "File
exists". Oops! the VMS system is bogged down with another rogue smbd. This
time, I have 100% CPU usage by SMBD_ANTIOCH-SP (last time there was a lot
of I/O).
