Hi everybody!
We've a legacy application based on Clipper, very important
for the company.
And we want to share the database and program files through
a samba server with Gentoo Linux.
But, when the users mapping the resource with a Windows 98, 2K
or XP client, the application run VERY VERY slow.
This application has been shared with Windows 98, 2K or XP
and run too much faster than Samba.
We tried tuning the smb.conf modifying parameters:
oplock, lock spin time, etc...
We have read the documentation about SAMBA in:
http://www.oreilly.com/catalog/samba/chapter/book/appb_02.html
http://www.drouillard.ca/Tips&Tricks/Samba/Oplocks.htm
We've tried with different schemas:
Filesystems: ext3, reiserfs, xfs, vfat with and without LVM2
and tried again, but with the same result: the application run
VERY slow.
Any clues on what could be the problem? and how to solve them?
Beforehand thanks!
The hardware in the server is:
Processor Intel Pentium 4 HT @ 2.80GHz
RAM 512MB DDR
HDD 80GB SATA
NIC Broadcom NetXtreme BCM5751 Gigabit Ethernet
samba version: 3.0.10
Gentoo version: 2005.0
kernel version: 2.6.11
and the last smb.conf version:
