I just have repeated the experiment on different machine, but with basically
the same config.
Result is quite strange:
setting the altq bandwidth to 100Mb, which is a lan-speed, doesn't results in
speed resuction -- I am still getting some 10MB/s transfer speed for scp.
Setting it to 10Mb, results in the transfer speed of approx. 750-820KB/s,
which is somewhat too low.
For 1Mb limit it's working again. ~120KB/s.
Same for 350Kb. Transfer ~40-44KB/s.
It's a bit strange because this two machine are identical from the software
point of view. All system, except /home, /var and a few files in /etc are
periodically synced between them.
Can it be due to the bfe network card in the problematic machine?
