Linux Kernel Size

LST · 02-15-2004, 04:07 PM

I am interested to see what the sizes are of other Linux Users' Kernels in comparison with other people and my own.

My Kernel size is 948Kb

SciYro · 02-15-2004, 04:37 PM

mine (not includeing System.map is 762084 bytes, i dont have usb suport, i use alsa modules pcmcia-cs modules (these are also not included), so i dont have a big kernel as i havent compiled what i probly wont/never will need to use for a laptop

You should include the kernel version as the later 2.6.x versions are significantly larger than the previous kernels.

I currently run 2.4.24 on all my machines except 2.6.0 and 2.6.1 on two different machines.

My 2.6.x's are between 1.5 - 2.0 megs and my 2.4.24 are around 1.2 megs. I remember getting 2.4.19 down to about 800kb average.

Yes - I am running Linux 2.6.2 on my Laptop which I use in school - About a week ago it was a massive 1.8Mb which is far too large, so I spent some time looking at the bits I need and don't need and then taking bit's out (It's supprising how many unneccerary things I compiled into the Kernel!). I am rather pleased because I now how a Kernel which I have reduced in size by about 48% and it also supports all my hardware!

Mandrake 9.1 kernel 2.4.21-0.13mdk. Is 1.2Mb

/bin/bash · 02-15-2004, 06:23 PM

Well up until around 2.4.15 I used to keep mine under 800k. Not anymore.

Code:

-rw-r--r--  1 root root 1014998 Nov 28 23:30 vmlinuz-2.4.23
-rw-r--r--  1 root root 1015071 Jan  5 08:30 vmlinuz-2.4.24
-rw-r--r--  1 root root 1233205 Dec 18 20:30 vmlinuz-2.6.0
-rw-r--r--  1 root root 1380435 Jan  9 10:30 vmlinuz-2.6.1
-rw-r--r--  1 root root 1338058 Feb  5 14:50 vmlinuz-2.6.2
-rw-r--r--  1 root root 1331149 Feb 10 19:31 vmlinuz-2.6.3-rc1

I use 2.4.20 and mine is around 700K . Not tried the 2.6 one though

So - Who else want's to post their kernel size and possibly version?

synaptical · 02-17-2004, 05:57 PM

1.4mb - 2.6.2
920kb - 2.4.24

DrOzz · 02-17-2004, 06:04 PM

main box :
2.6.2 - 1.6mb
web server :
2.4.20 - 1.1mb

Interesting how this has grown over the years. Here's a recent Fedora kernel:

Code:

ls -l /boot/vmlinuz-5.16.18-100.fc34.x86_64 
-rwxr-xr-x. 1 root root 11312336 Mar 28 11:02 /boot/vmlinuz-5.16.18-100.fc34.x86_64

Given that this thread is over a decade and a half old, I think it's safe to say that the kernel has increased in size a wee bit over the years.
