See KernelCompilationTimes for the 2.6 series benchmark.

Both sets of times below are compiling a standard linux-2.4.19 kernel. Configured with the defualts for everything.

(In /usr/src, with the 2.4.19 source downloaded already...)

tar zxvf linux-2.4.19.tar.gz cd linux-2.4.19 make oldconfig /usr/bin/time -p -o /tmp/dep.time make dep /usr/bin/time -p -o /tmp/bzImage.time make -j 2 bzImage modules

If you have a machine with more than one processor, you can use make -j n .... where n is the number of cpus + 1

Note: the /usr/bin/time -p -o ... etc is to save the output from time into the specified file, and use the same format as bash's built in 'time'. sigh
