=====================

Hi list,

Sometimes ago I noticed a samba slowing down but as I don't use it 
very much it was not a PB (NO conf changes.)

Today I made this test on CLI:
mount -t cifs //svr/myshare /mnt/ -o username=myuser,password=mypw,ro
then: 
cp /mnt/films/20090911_0025_footage.avi . (this one's 2GB)

The speed (measured w/ iptraf) is terribly slow (~750KB/s), so I made 
another test: ftp using filezilla: ~7500KB/s (!)

There's nothing special in my conf file, and I've got a line as doc say:
socket options = TCP_NODELAY IPTOS_LOWDELAY SO_RCVBUF=8192 SO_SNDBUF=8192

I really don't understand why there's so much difference between samba & ftp
mostly because formerly (well, may be a year ago) there was only a very small
gap between these speeds.
