Would you try latest ale(4) at the fowllowing URL? > http://people.freebsd.org/~yongari/ale/ale.20081110.tar.gz 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.
