This is breakage on the Windows XP client. There's nothing
you can do except not use Windows, sorry. This is just what
those clients do.

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

2006-09-21 Thread Alain . Gorlier 
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\1files\*.* 
c:\data\1files

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 :
No. TimeSourceDestination   Protocol
