Hi folks, Having to migrate a Proxy server from an Ultra SPARC (u10) to FreeBSD I was looking for similar kernel tunables as the ones I tuned on Solaris. The new system is running FreeBSD 4.7 Stable on a SMP machine with two very fast SCSI disks and 1 GB of RAM.
I did a man tuning, read the relevant sections on the FreeBSD handbook, searched google and looked at the relevant sections of the FAQ on www.squid-cache.org. This is what I have done so far; /boot/load.conf kern.ipc.nmbclusters=131072 /etc/sysctlt.conf kern.maxfiles=65536 kern.maxfilesperproc=32768 kern.ipc.somaxconn=8192 net.inet.ip.portrange.last=30000 net.inet.tcp.sendspace=65535 net.inet.tcp.recvspace=65535 net.inet.tcp.slowstart_flightsize=2 net.inet.udp.maxdgram=57344 net.inet.udp.recvspace=65535 kern.ipc.shm_use_phys=1 #ok no undesirable overhead> vfs.vmiodirenable=1 #ok <set explicitly, cache as much directories as you can> # harden the stack a bit net.inet.icmp.drop_redirect=1 net.inet.icmp.log_redirect=1 net.inet.ip.redirect=0 net.inet.ip.sourceroute=0 net.inet.ip.accept_sourceroute=0 net.link.ether.inet.max_age=1200 #ok <set explicitly> net.inet.icmp.bmcastecho=0 #ok <set explicitly> The system is a dedicated web Proxy server processing approximately 236 GB a month. During peak hours the total request per seconds is nearby 65 and the client_http.all_median_svc_time = 0.045193 seconds. During peak hours the average load is around 0.50. The above tuning has a considerably effect on the performance of the web cache server and it is performing like expected.
