for 10 GBE 70 MB/sec are a joke to start with, any average 1 GBE network 
can do that and given that samba has a lot of roundtrips when your 
network has general problems with SMB they are always much worser (just 
look at the horrible performance over OpenVPN)

[harry at rh:/downloads]$ scp harry at remote-machine:/www/bench.bin ./

100%  256MB  94.2MB/s   00:02
