samba - Sep 2002 - MS-Access Application very slow

Hi,

I changed the NT-Server to Samba about one year before, and everything worked 
fine. I did this, because I frequently need remote access to the server via 
ISDn-line and do not want to wait for Win-Stuff beiing transmitted before I 
can start working.

There are several MS-Access-Databases on the server, used by one or more 
users without problems.

But now they bought an application "programmed" with MS-Tools with
MS-Access
"Database" (Sorry, I could not prevent).
This thing works quite o.k., when the files are placed on a share of win98 
client, but most operations take up to ten times as much time when the files 
are placed on the samba ( SuSE-Linux 7.1, Samba 2.2.5 - freshly installed ).
The server has a bit elder processor ( PIII 600 MHz with 256 MB RAM, SCSI 
system with a 9 GB and a new 18 GB HD, the MS-access-files single on the new 
drive), in the kde-tool, the CPU does not seem to be very busy, there ist a 
lot of memory used for caching, no use of the swap-partitions.

The clients are all win98, Intel P4 1200MHz, 256 MB RAM.


If I do an ftp-download from the server to any win-client, I get 8300KBit/s 
data throughput, a simple copy with the MS-explorer also goes well (It does 
not show how fast it is running, but the time seems to be o.k.) .

Has anyone an idea, where I could look for ?


thanks

Martin

man smb.conf

	kernel oplocks
	blocking locks
	fake oplocks
	level2 oplocks
	oplocks
	locking


Check it with "smbstatus", if they acces to this files.

Please, let us know, how to solve this problem.
