Hello list,
please spend a minute considering these facts and maybe there is something to 

1) VIA Eden based board can write AES256 encrypted information on HDD at > 
2) iperf shows NIC speed 69MB/s
3) openssl tests have even better results
4) openssh can transfer AES256 encrypted information at < 27MB/s (and worse 
with HDD encryption)

It is better with openssh 5.x, than 4.6, but still I see no reason why results 
are so bad... Please, could someone explain? I don't believe, padlock is used
