Is there a particular advantage to compiling a new kernel?


Perhaps I'm missing out on something, but everything seems to be working as I want it to with the standard kernel. So is there anything I'd gain by compiling a new kernel?

well..if all works oke, i don't think there's a need to do that.
but you could try and learn how it works anyway, so when running into some prob's
in the future ( requiring a kernel-compile ) you know what to do.

so ....if you have some spare time, just try it.
( just get the latest sources at www.kernel.org and read the sticky howto on this forum )
and it's fun too

Yuh, the one major advantage would be learning as mentioned by egag.

It also deepens the desire to know more and sqeeze the juice out of Linux.

For me, I get my 1Gbyte of RAM recognized by compiling in Big Mem, sometimes smaller kernel (sometimes - when I am careful and attentive). And also I can follow the kernel trail of "upgrades"

I was afraid i was going to hear that. Right now my system only recognizes 896 MB of RAM:
Code:
Linux version 2.4.26 (root@tree) (gcc version 3.3.4) #6 Mon Jun 14 19:07:27 PDT 2004
BIOS-provided physical RAM map:
 BIOS-e820: 0000000000000000 - 000000000009fc00 (usable)
 BIOS-e820: 000000000009fc00 - 00000000000a0000 (reserved)
 BIOS-e820: 00000000000f0000 - 0000000000100000 (reserved)
 BIOS-e820: 0000000000100000 - 000000003fff0000 (usable)

 BIOS-e820: 00000000fee00000 - 00000000fee01000 (reserved)
 BIOS-e820: 00000000ffff0000 - 0000000100000000 (reserved)
Warning only 896MB will be used.
Use a HIGHMEM enabled kernel.
896MB LOWMEM available.
I also have 1G of RAM.
Well on the other hand my pc never uses more that 600MB of RAM or any swap memory. (I had 256 MB of RAM and i have a 512MB swap partition created when i installed fedora). I don't think i need a swap partition anymore at all.

But as a responsible linux user i think I should start behaving like a man and do a kernel compile.

That's the spirit. As many have said here before, "If it ain't broke, tweak it till it breaks."

Have fun!

You'd also get the chance to optimise it more specifically to your processor architecture, which might yield some improvement in performance.
