[Samba] Weird problem of slowness on 3.2.5

[Michel Lombart]

Hello everybody.

We had a Samba 3.024 on a old computer. It's disks begun to fail and we 
decided to replace the computer with a new one. I installed a Lenny and 
a Samba 3.2.5.

I've two problems of slowness :

     * If I open a large pdf ( around 5 Mbytes ) on any computer and if 
I want to print it ( directly from the computer to the printer, we do 
not use Samba as a print server ) that takes a very long time for the 
first page to be sent to the printer. With the old server, that took 
only some seconds. If I transfer the pdf on the computer and print from 
it, all is perfect.
     * A software running on multiple computers is very slow since the 
setup of the new server. It has some data files ( 10 ) on the samba.

These happend on every workstation or laptop we have !

When I navigate into the new Samba's shares, I do not notice any 
slowness neither when I open a document. I tried to transfer a huge file 
and It was done with a speed nearly my network card capacity ( 100 
Mbits/sec ).

The load of the server and it's memory usage are very slow. All shares 
are open read/write to everyone.

Any idea to solve it ?

This is my config file. Thank for your help.

Michel.
