Reducing kernel compilation time

[Camaleón <noelamac@gmail.com>]

Hello,

I had to compile the latest upstream kernel sources to make some 
debugging with my wifi drivers (from staging) and discovered that 
compilation took ~5 hours.

That's much for testing purposes.

Compilation takes place in a netbook governed by Intel's Atom N455 with 2 
GiB of RAM and I would like to reduce the compilation time.

I'm using the same ".config" file I have for the current Debian stock 
kernel (to avoid missing some modules I may need) and just added 
"CONFIG_MATOM=y" but it takes almost the same time.

I don't need nothing special, just to be able to boot the system, test 
the staging drivers and then remove/compile a new kernel again so wasting 
the less time in the process would be great :-)

Any trick?

Greetings,
