Hi Gerald,

Good thought but I consider jumbo frames and ip stack tuning the topping if everything works ok. The smb.conf is basically empty, except for needed things of course. No tuning, no other peculiarities. I have a second box that is working ok, different m/b, same onboard nic, same samba version but pure Debian Wheezy and not Proxmox (on Wheezy). Have to dig that way...
