Indeed, not so much kernel options, but filesystem options would likely benefit you the most, especially if you can determine ahead how big your average file size will be. -- -- ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]
Re: Kernel Options fo a File Server
From what I heard from most BSD'ers it's not really feasible to re-compile or customize the kernel much these days. If you truly need to compile/optimize the kernel you're already overworking your hardware. With that being said I’m curious myself, I'm always interested in squeezing a little out of my hardware.

Thanks. I typically recompile a kernel for almost every new machine. You can certainly change a great deal of options within the kernel that you otherwise can't do. For instance do a 'make LINT' in /usr/src/sys/i386/conf and grok the LINT file for options. There are tons of tweaks you could do. If you want to tweak the file server I would look more into tunefs. man tunefs...this will probably be where you will find the most info about getting the most out of your filesystem. -Tom ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]

(Please don't top post.) Recompiling the kernel and customizing it (i.e. leaving things out that you don't need) are not very hard at all. Things like enabling kernel thread preemption and file system softupdates might help with performance. But in general you could say that removing code for devices and subsystems that aren't used anyway might speed up booting a bit, but will not help much with speeding up daily usage. The tuning(7) manpage gives lots of tips on getting the best performance out of your system. Note that the kernel occupies only a small section of the material in that page. For instance, for a file server the file system layout is much moe important due to higher transfer speeds from the outer edges of the disks.

Thanks, Ivan Even with a GENERIC kernel you're going to be disk-bound, unless you have them in RAID 0, in which case you'll be network bound. If you are running i386 you can take out 486 and 586 support, that's probably the biggest single improvement you can make, and it's incremental at best. --- Thanks, Josh Paetzel ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]
