Do you actually mean that it requires 40+ minutes for you to compile a
kernel?

I have been compiling kernels for years and it's always been about 2

It must be the kernel configuration.  I configure the kernel to include

What is the size of your compressed kernel image?  This is the file

Note that the "bz" does not necessarily indicate that bzip2 compression
is used.  The particular compression algorithm is set at kernel
configuration.  Mine uses LZMA.

 
 
Why do you guys even do this shit?  My kernels are downloaded as
compiled binaries, already, generic, it doesn't hurt anything.  It's
just like using Windows, but without M$'s crud bloating it.  It's a
dream.

I like wrenching on my OS, like some people wrench on their hot rods.
Might even find a bug, in which case I can a) report it,
b) possibly with a fix.

As I've said numerous times, I build a "kitchen sink" kernel, basically
with all the modules.  _ALL_ the modules, not the subset FF is building.
(I started with the Linux Mint low-latency .config several kernels ago,
and have been migrating that ever since.)

That way, if the compilation spits out a diagnostic for anything,
I'll know about it.

If I wanted to, there's a make target for "localmodconfig" which will set
up the build system to only make the modules that are loaded.  But that
can leave out (say) iptables modules, which would be a pain if I went and
tried to use something new.  So, I build _all_ the modules.

What I would like to do is someday figure out how to build
with -march=native .  Haven't bothered yet, because my machine is already
plenty fast.

Finally, the bottleneck for building the kernel in that last run is
compiling on an NFS share...
