How do I try a different set of compile options nowadays?
I change it in CC .config, it changes back.
Used -O2 in cero...
python, for example, is way slower than it was.

new box: 3.280u 0.080s 0:03.36 100.0% 0+0k 0+0io 0pf+0w
there's slow and then there's slow

OpenWRT normally sets it in the Build Options section of the menuconfig.
