I also want to do tuning kernel + dummynet + ipfw using sysctl and load.conf .I am using Xeon 2.4 Server with 2 broadcom Giga lan Cards and 32 GB SSD and 2 GB RAM and I will bandwidth shaping for each ip means every /32 for 4000 IP addresses. I try to google for tunning these follwoing Dummynet settings but could not dig deep into it. I love to know about every settings (use / min value / max value / best value ) same for ipfw and tcp settings For example: net.inet.ip.dummynet.io_fast: 0 (what is this use for / min value / max value / best value) net.inet.ip.dummynet.ready_ heap: 64 (what is this use for / min value / max value / best value) net.inet.ip.dummynet.hash_size: 64 (what is this use for / min value / max value / best value) and the rest of settings but I love Know about them ...... if any one know about any book , ebook , tatorial etc etc etc then please reply 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 Thanks TheONe KHan
