Hartmann" To: freebsd-stable@freebsd.org Cc: freebsd-questions@freebsd.org Subject: kernel option NBUF, what does ist means? Message-ID: MIME-Version: 1.0 Content-Type: TEXT/PLAIN; charset=US-ASCII Sender: owner-freebsd-questions@FreeBSD.ORG Precedence: bulk X-Loop: FreeBSD.ORG Dear Sirs. For non kernel developer the additional options in LINT for kernel configuration are little secrets and it is said, that some of them could 'tweak' a standard kernel to be more powerful when getting tweaked and the system it runs on is to be a server (I read some articles about Linux vs. FreeBSD in a German magazine and it has been mentioned that tweaking makes FreeBSD faster for serving purposes). One of the secret parameters seems to be NBUFS. it is set to 512 in LINT, I set it to 4096 this time to see whats going on. Can anyone offer me a hint on this parameter? For servers which are accessed as SAMBA and Webservers, what parameters are worth to be watched and set? What parameters (those are not explained) are useful for machines which should act as number crunchers? Thanks in advance, Oliver - MfG O.
