This makes me wonder,what would be the best way to test the performance
of the kernel under different optimizations? I never did any real
kernel benchmarking and never been much interested in it so far... but
there must be tools for it! :-)
lmbench or so?
Then I could compile some stats for the kernel compiled with different
options (-O2, -06, -Os, and perhaps there are other useful options to
It might be useful to have something like that documented somewhere! :-)
