Great, thanks! The perfomance is returning back. ;-) It shows
approx. 10.5 MB/s while ftp'ing a big file to tmpfs. I'd like to show
you some additional info:
-----
uname -a ftp://ftp.bsam.ru/pub/tmp/EeePC/uname.2
netstat -w 1 ftp://ftp.bsam.ru/pub/tmp/EeePC/netstat.ale.2
sysctl dev.ale.0.stats ftp://ftp.bsam.ru/pub/tmp/EeePC/sysctl.ale.stats.2
iostat -w 1 ftp://ftp.bsam.ru/pub/tmp/EeePC/iostat.ale.2
-----

The interesting one is a netstat one. I'm not sure what zeroes for
packets mean while trafic exists.

BTW, a flood ping created a 233 packets per second trafic.
