All,
Please help me defend Samba.
We are having major performance problems when using VisualStudio
to build projects. The source lives on the server, and the intermediate
files are dumped locally to try to speed things up.
One of the engineers downloaded a demo of NetManage/Chameleon NFS and
it was significantly faster. Here are some numbers:
samba-1.9.18p8 samba-1.9.18p8 samba-2.0.3 ChameleonNFS
No oplocks oplocks oplocks
-----------------------------------------------------------------------
Project "A" 30 minutes 31 minutes 24 minutes 9 minutes
File "A.cxx" na na 25sec 10sec
Those are drastic differences.
With 'oplocks' on, we are having problems of WinNT clients picking
up changes made on the server. Yes, I have read the note here, but
we *are* running Samba on IRIX 6.2 with kernel oplocks ON.
Please send reply to vince at rti.com. Thanks for any help!!
