Question is which of these documents should one follow to actually set = kern.maxfiles or possibly others for that matter? From: http://www.kegel.com/c10k.html#limits.filehandles=20 "FWIW: You can't actually tune the maximum number of connections in = FreeBSD trivially, via sysctl.... You have to do it in the /boot/loader.con= f file.=20 The reason for this is that the zalloci() calls for initializing the = sockets and tcpcb structures zones occurs very early in system startup, in = order that the zone be both type stable and that it be swappable.=20 You will also need to set the number of mbufs much higher, since you will = (on an unmodified kernel) chew up one mbuf per connection for tcptempl = structures, which are used to implement keepalive."=20 From: http://www.daemonnews.org/200108/benchmark.html=20 "sysctl A few sysctl variables should be tuned for maximum performance. The = following lines were added to /etc/sysctl.conf:=20 vfs.vmiodirenable=3D1 kern.ipc.somaxconn=3D4096 kern.maxfiles=3D65536" To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
