Need Help with dummynet sysctl settings or tuning

[tvtube blog]

Thanks Rocha for the help but i think you took it in wrong ways I know about
these rules I am use to play these rules ... I just want to optimize Freebsd
8 , dummynet and ipfw.

I want to optimize below setting and want to know about its use ...   like (
why , min value , max value , 0  or 1 , on and off ).

Firewal# sysctl -a | grep dummynet
net.inet.ip.dummynet.debug: 0
net.inet.ip.dummynet.pipe_
byte_limit: 1048576
net.inet.ip.dummynet.pipe_slot_limit: 100
net.inet.ip.dummynet.io_pkt_drop: 928
net.inet.ip.dummynet.io_pkt_fast: 132
net.inet.ip.dummynet.io_pkt: 649566
net.inet.ip.dummynet.io_fast: 0
net.inet.ip.dummynet.tick_lost: 0
net.inet.ip.dummynet.tick_diff: 247710
net.inet.ip.dummynet.tick_adjustment: 247672
net.inet.ip.dummynet.tick_delta_sum: 665
net.inet.ip.dummynet.tick_delta: 1000
net.inet.ip.dummynet.red_max_pkt_size: 1500
net.inet.ip.dummynet.red_avg_pkt_size: 512
net.inet.ip.dummynet.red_lookup_depth: 256
net.inet.ip.dummynet.max_chain_len: 16
net.inet.ip.dummynet.expire: 1
net.inet.ip.dummynet.search_steps: 662611
net.inet.ip.dummynet.searches: 649566
net.inet.ip.dummynet.extract_heap: 0
net.inet.ip.dummynet.ready_heap: 64
net.inet.ip.dummynet.hash_size: 64


Like what I only under stand from net.inet.ip.dummynet.debug: 0  that If I
make it net.inet.ip.dummynet.debug: 1 then debug will start and we gave out
some out put in /var/log/message. same like this is want to know about rest
of them.

Thanks in advance ad hope now you all under stand me ... sorry for bad
english
