Anyone can give me a real life example, full ipfw traffic shaping ruleset or something like that.

FWIW, here's the shaping section from my ipfw setup. I'm behind an ADSL2 line, so I don't care about downstream bandwidth, but I do about the upstream. This allows me to run BT at full rate and still have decent ssh interactive and web browsing behaviour.

${fwcmd} pipe 1 config bw 480kbit/s

# up prio: TCP ACKs, SSH interactive, etc.
${fwcmd} queue 1 config pipe 1 weight 100 queue 20 mask all
# up std: everything else
${fwcmd} queue 2 config pipe 1 weight 50 queue 20 mask all
# up bt: bt etc.
${fwcmd} queue 3 config pipe 1 weight 1 queue 20 mask all

# favour small TCP packets (ACKs)
${fwcmd} add 200 queue 1 tcp from any to any iplen 1-100 xmit tun0
# ssh
${fwcmd} add 201 queue 1 tcp from any to any 22 iptos lowdelay xmit tun0
# DNS, NTP
${fwcmd} add 202 queue 1 udp from any to any 53, 123 xmit tun0

# BT etc.
${fwcmd} add 210 queue 3 tcp from 192.168.0.0/24 21530-21539 to any xmit tun0
${fwcmd} add 211 queue 3 tcp from 192.168.0.0/24 6880-6889 to any xmit tun0
${fwcmd} add 212 queue 3 tcp from 192.168.0.0/24 to any 6880-6889 xmit tun0

# default
${fwcmd} add 220 queue 2 tcp from any to any xmit tun0
