[Samba] Long Delays Displaying Small Folders in Windows Explorer (samba-3.0.10-1 FC2)
Hi,
I'm trying to replace a windows fileserver server with a Fedora Core 2
samba server in our Windows 2000 ADS domain.
A performance problem occurs when accessing certain samba shares from
Windows Explorer on either an Windows XP or a W2K client machine. It
can take up to a minute for explorer to list files in a share folder
containing only a few files! It eventually does, but but reports as non
responding for a long period beforehand.
I've gone about as far as I can in attempting to resolve this issue
myserlf and would appreciate any suggestions from the samba list!
Server Hardware:
HP Proliant ML 350 Xeon 1G mem
NetXtreme BCM5705_2 Gigabit Ethernet
Server Software
All FC2 packages updates applied as of early May 2005 including:
smp kernel 2.6.10-1.771
samba 3.0.10
Network Hardware
Linksys and 3com Switches (circa 2004)
Client hardware:
Windows 2000 SP4 and Windows XP Pro machines
In setting up the samba server, I followed the approach outlined in
"Samba-3 By Example" chapter 9.3.3 "Active Directory Domain with
samba
Domain Member Server". I also applied recommended tuning steps. The
setup all seemed to go impressively smoothly.
I suspect the problem is related to networking. Analysis in ethereal
shows a huge amount of traffic during the non responsive period. It
looks like every file is read in it's entirity in 512 byte increments?
Also, a lot of checksum messages come up.
Two highly abreviated text extracts from the ethereal logs are attached
(which are repeatable):
The first shows the (61 entries) activity involved in displaying
share //nghfs/downloads - which occurs quickly.
The second shows a sample of the excessive activity (57000 log entries!)
involved in displaying a sub folder share //nghfs/downloads/Mozilla -
which takes quite a few seconds although only contains 5 files and 2
folders.
The smb.conf file is also attached.
Any help is most welcome,
Stewart.
