squid performance and kernel tuneables
Hi folks, Having to migrate a proxy server from a ultra sparc (u10) to FreeBSD I am looking for the appropriate kernel tuneables. The new system will run FreeBSD 4.7 Stable on a SMP machine with two very fast scsi disks and 1 1/2 GB of RAM. I did a man tuning, read the relevant sections on the freebsd handbook searched google and looked at the faq at www.squid-cache.org. This is what I have so far; kern.maxfiles: == 65536 kern.maxfilesperproc: == 32768 kern.ipc.somaxconn: == 8192 kern.ipc.nmbclusters: == 131072 net.inet.ip.portrange.last: == 3 net.inet.tcp.sendspace: == 65535 net.inet.tcp.recvspace: == 65535 net.inet.tcp.delayed_ack: == 0 net.inet.udp.maxdgram: == 57344 net.inet.udp.recvspace: == 65535 kern.ipc.shm_use_phys: == 1 vfs.write_behind: == shouldn't this be turned off for web cache systems ? kern.ipc.shm_use_phys: == ok vfs.vmiodirenable: == ok For diskd the FAQ on www.squid-cache.org is clear about the kernel tuneables. It is the above settings which I want to know more about. My question to the list is as follows; Are there any kernel tuneables paramater above which are set wrong or which are plain irrelevant for a high performance http proxy server on FreeBSD ? and are there any relevant parameters (besides that for diskd) which are not included in the above list ? The system will be a dedicated http proxy server processing approximately 236 GB a month and like 216426 request per hour. tnx, Lucio Jankok To Unsubscribe: send mail to [EMAIL PROTECTED] with "unsubscribe freebsd-questions" in the body of the message
kernel tuning and Squid performance
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=3 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 # 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 net.inet.icmp.bmcastecho=0 #ok 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.

RE: bge network driver not loaded on a HP (Compaq) Proliant DL380 G3
Had this problem with 4.7 Release. 4.7 Stable solved this problem. The driver is rock solid too.. processing more than 230 GB a month.

Re: Interface collisions
collisions means half duplex if you don't want them, do something like this with your fbsd box; #in rc.conf ifconfig_bge0="inet 192.168.141.90 netmask 255.255.255.0 media 100baseTX mediaopt full-duplex" and your switch must be set on 100 fdx also.

Re: mail server
you may want to try postfix.. read the docs as usual.. if someone can tell you something it is because they read the docs or source too..
