[Samba] Poor performance getting lots of small files with WinXP/Win2k vs OS2

Hi,
We're doing some of performance tests with Linux Samba v3.
We're comparing WinXP/Win2k clients vs OS2 clients accessing a samba 
server.

For one test, we're coping 10.000 small files.
Let's say, we run the command copy \\sambaserver\10000files\*.* 
c:\data\10000files

With an OS2 client it takes 23 seconds to complete.
With an Windows client it takes  460 seconds to complete.

Doing a Ethereal capture, the network usage is very different.
OS2 :

So, the performance difference is easy to explain....

Is there a way to avoid such network usage on a winXP client ?  At the 
client side ? At the Samba server side ?
Looks like it's related to the Windows NTFS environment....
We've tried to define the Samba share drive as a samba drive (fstype = 
samba in smb.conf), but the performance remains the same ....

We're currently looking for a migration plan from OS2 clients/OS2 Lan 
servers to Windows Clients/Samba servers. We may encountered response time 
problems at the Win client side and CPU/Network load problem on the samba 
server side....

Is there some recommandations regarding copying lots of files for Windows 
clients ?
Is there some recommendation regarding Application Developpement for 
Windows accessing Samba servers ?
