Performance problems

[Richard Furda]

	Hello,

I am having performance issues with Samba version 2.0.6.
Server is a FreeBSD 5.0-CURRENT, client is WindowsME.
Both use Intel Express Pro 100+ NICs. Connection is
100BaseTX/full duplex, CAT5 crossover.

I performed the following tests with a 687MB binary file.

 o FTP
     FreeBSD  =>  Windows   190 seconds
     Windows  =>  FreeBSD   257 seconds

 o SMB	
     FreeBSD  =>  Windows   225 seconds
     Windows  =>  FreeBSD    30 minutes   (*)


This same problem occured while I ran Windows98 on the client side. 
My Samba has the following configuration related to performance:

socket options = TCP_NODELAY IPTOS_LOWDELAY IPTOS_THROUGHPUT 
read raw = yes
write raw = yes
max xmit = 65536
read size = 16384
shared mem size =  6291456
oplocks = true
level2 oplocks = true 
read prediction = True

FreeBSD kernel has the following options as well:

options         SHMMAX=(SHMMAXPGS*PAGE_SIZE+1)
options         SHMMAXPGS=2048      # 8192KB of shareable memory

I believe this problem is not related to Windows tcp/ip stack,
the driver or the cabling, but Samba.
