I had some problems in the past with oplocks and this behaviour was seen
on Windows machines. In samba logs I saw something like (don't remember
exactly) "waiting for oplock to break".
The easiest way to produce this was to open many (eg. 20) .xls files at
the same time. (Ctrl-A on all files in directory and Open).
And the default time for oplock break is 30 seconds.
This was with 2.2.x samba. Since then I have oplocks off. Haven't tried
to switch them on on 3.0.x.
