Note

These results may be seriously flawed!

I tried the "yes "" | make config" directive, but the compilation result was totally different on different machines! (the kernel directory took on one machine only <400MB and on the other machine 2.1GB)

I suggest uploading a standard benchmark kernel config here.

I also suggest posting the user+sys times so we can at least somewhat exclude the harddisk contribution.

Introduction and rationale for the choice of the benchmarks

The first benchmark will be the kernel compilation we will use the 2.6.4 kernel in order to be able to include some result of famous test websites. Note that this kernel will not compile under GCC 4, and that comparing compilations using different compilers is not strictly correct. To download and untar the kernel

wget http://www.kernel.org/pub/linux/kernel/v2.6/linux-2.6.4.tar.bz2
tar xvjpf linux-2.6.4.tar.bz2
cd linux-2.6.4

and then type:

yes "" | make config
time make

then you have a result like this:

real 13m52.139s
user 12m42.036s
sys   1m2.388

so the compilation time is 13m52.139s

user is the time spent in usermode
sys is the time spent in kernel mode
This information is very usefull when benchmarking others linux distributions:some have 32 bit userland and 64 bit kernel for 64 bit processors(not necessarly x86_64)
