average loaded site (about 1000 users), fast machine, lots of ram, fxp interfaces (no realteks), squid reports 32768 filedescriptors available [root@w3cache ~]# limits -U squid Resource limits for class squid: cputime infinity secs filesize infinity kB datasize infinity kB stacksize infinity kB coredumpsize 0 kB memoryuse infinity kB memorylocked infinity kB maxprocesses 64 openfiles 32768 sbsize infinity bytes vmemoryuse infinity kB [ /etc/sysctl.conf: kern.ipc.somaxconn=65535 kern.ipc.nmbclusters=32768 net.inet.tcp.delayed_ack=0 net.inet.icmp.icmplim=500 vm.defer_swapspace_pageouts=1 net.inet.tcp.sendspace=65536 net.inet.tcp.recvspace=65536 kern.ipc.shmseg=128 kern.ipc.shmall=16384 kern.maxfiles=65536 kern.maxfilesperproc=32768 kern.ipc.nmbclusters=131072 net.inet.ip.portrange.last=65535 vfs.lorunningspace=3145728 vfs.hirunningspace=6291456 net.inet.tcp.msl=5000 vfs.root.mountfrom="ufs:ad0a" kern.cam.scsi_delay="1000" kern.ipc.msgseg=1024 kern.ipc.msgssz=128 kern.ipc.msgtql=8192 kern.ipc.msgmnb=65536 kern.ipc.msgmni=100 kern.ipc.msgmax=8192 kern.maxproc=1000 kern.maxbcache=134217728 kern.dfldsiz=2147483648 kern.maxdsiz=2147483648 in dmesg i found lots of ipfw: pullup failed CPU load is always <10%, it's P4 machine with 2GB ram (much more than squid uses) running FreeBSD 6.2-RC1, 3 interfaces - out output, 2 for different connections, ipfw is used with only 1 line. any more ideas?
