[Samba] Client link utilization

Hello everybody!

This is probably going to be a classic question but I cannot find a
decent answer on net.

I have samba server set up and the following things work flawlessly:
- iperf shows 92% link utilization
- FTP/SCP/HTTP transfers work in 10MB/s range.

However, when I mount samba share with linux client (mount.cifs) the
link utilization cannot bypass cca 33%. Transfer speeds constantly
stops around 3.8MB/s and will not rise above it no matter what socket
and locking options I use.

Do you have any ideas about why this is happening and/or FAQ websites
to point me to?

Thank you very much,
