I have four Dual Pentium II 333mhz computers (DK440LX motherboards), 512MB of memory each, all running on 100Mb switched ethernet, 9 gig SCSI-2 Cheetahs, and everything is running great, until I experience heavy load. Two of the computers are running MySQL databases (one processing more than 2,000,000 transactions per day, the other processing more than 4,000,000 transactions per day). The other two computers are running Apache 1.2.5 + FastCGI, and processing upwards of 7 million hits per day combined. Obviously, I'm using a lot of file handles and sockets, and as I experience super heavy load (anything more than it is now), I start seeing a rash of errors due to, what I think, is an improperly configured kernel. FreeBSD 052098-SNAP, some of the kernel configuration: maxusers 512 options NMBCLUSTERS=4096 options "CHILD_MAX=512" options "OPEN_MAX=512" options SYSVSHM options SYSVSEM options SYSVMSG also, I do this is /etc/rc.local: /sbin/sysctl -w kern.ipc.somaxconn=4096 /sbin/sysctl -w kern.maxfiles=16384 ------------------------------------------------------------------------------ Questions: How else do I optimize this machine for more load? What the heck is an NMBCLUSTER anyhow? ------------------------------------------------------------------------------ Thanks so much for any help you can give!
