All, Im getting ready to go with our FreeBSD production mail server and Ive been reading that to optimize network mbufs, specify the NMBCLUSTERS options in the kernel. Ive read that setting this to a quarter of your physical RAM on this is the way to go, or devising a number from a mathematical equation based upon your maximum number of connections at peak (meaning, 800 connections at peak equals an NMBCLUSTER of 25600, or mathimatical breakdown 800 connections X 32K per session = 25600KB) Does anyone have a good way to devise a number for this, or is it really even needed? Ive a GB of memory in a Compaq DL320. The FreeBSD handbook says typically this is set to 1024 - 4096, adding to my confusion of what I need to set this to, if anything. Thanks in advance for any insight, Craig ------------------------------------------------- This mail sent through IMP: http://horde.org/imp/ To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
