Samba Performance

[Rashkae]

The documents you were testing, did they happen to contain any embeded OLE
objects?  There was an issue discussed on the list recently (You'll have
to search the archives,) but it appears that when MS Office opens a
document with embeded OLE objects, it attempts to make a connection to
some un-SMB related port on the remote computer where the file is being
opened from. (In the case of Samba, there is nothing listening on this
port, so you have to wait for the operation to time out.) I don't believe
anyone here was able to explain this behaviour, but detecting it via log
files / network monitoring was somewhat well discussed.

On an asside, I really think you should update your SAMBA to the lastest
2.2.2 in CVS.. 2.2 release has been plauged with numorous little hard to
reporduce quirks, most of which seem to be fixed.

I have been testing out Samba as a possible replacement for our current Netware
4.11 server and I am a bit puzzled by certain performance aspects. I have Samba
shares on a Suse 7.3 box running Samba 2.2.1a and the performance seemed to be
fine but I noticed that when I opened Word or Excel files there was a 10-12
second delay before the data was loaded. When I switched my client from Windows
NT 4.0 to Windows 2000 the delay seemed to go away till I found that though the
data came up immediately I still didn't get back control of the mouse for about
10-12 seconds. I then tried opening the same files using OpenOffice and the
file loaded in less than a second so I don't think that it can be Samba.
Unfortunately our standard Office suite is Microsoft Office97/2000 so I need to
find out what is going on. Is this a known issue or has anyone else seen this
behaviour?
