[Samba] performance

[Nick Potemkin]

Hello.

I've got:

hardware
1) PII-350
2) 512Mb mem
3) RAID controller Adaptec 3200S I2O (two channels), 64bit PCI, but attached to
32 bit PCI slot.
4) 6 SCSI LVD drive in external box, attached to one channel of controller and configured as RAID-5
5) aic7xxx with system drive

software
1) debian 3.0 (woody)
2) kernel 2.4.18
3) samba 2.2.3a-6 (from woody)
4) winbindd
5) reiserfs on RAID mounted with (rw,noexec,nosuid,noatime,nodiratime,notail)

And i've got the problem:
Our designers has got program quarkXpress. When this program opens file for
makeup - it checks for changes many many files (may be 10 or 2000), associated with opened. It does many open/close cycles ( i saw it in samba logs). And on my configuration it works very slow :( Designers say it worked faster on NT server (on the same hardware, but without RAID).

Now i need your advices :)

; It's example of one share. All other shares are the same.
