samba - Mar 1998 - NetBench fails when using oplocks

We have been trying to get performance results for Samba using NetBench. 

When oplocks were not enabled the performance was poor.  The throughput
was approx 70% of that of a pc based NFS client. 
When oplocks were enabled the test failed to complete.

The version of Samba was 1.9.18p2
The server was a sparc station 20.

The version of NetBench we were using is 5.01
The test was the default test (using the disk mix suite) 
The number of clients was 2.

Nigel,

	What were the errors you got ? I have run NetBench
5.01 on a Solaris server with 60 clients and NetBench
completed successfully (reliably and with good results).

There are several 'tricks' in using NetBench that the
authors recommend than can make a great deal of difference
between success and failure. Are you doing a reinstall
between each run (believe it or not this is recommended).

What were the client OS's, what was the controler OS ?
(The best mix seems to be NT controler, Win95 clients).
