Hi,
I?ve recently migrated to a Samba3 server and everything seems to be running
well apart from a problem with some users that run macros in MS Access.
I?m told that a process which used to take 15min on the old W2K server took
over an hour on the new samba box.
After having a scan through the archives I think the problem may be related
to oplocks/locking but I?m pretty sure I?ve got these setup OK.
Checking usage through top and vmstat shows that the server isn?t overloaded
so I guess there may be a problem in my config somewhere.
If anyone has any ideas please let me know.
Thanks
The box is running RHEL4, kernel version 2.6.9-11.ELsmp and
samba-3.0.10-1.4E.
