Actually, these days, that also applies on the fat desktop. The default build options on the Linux kernel went from -O2 to -Os over a year ago, as it produced both smaller *and* faster code. Cache misses are now so expensive that (e.g.) unrolling loops is no longer worth it on modern processors, as you push too much code out of the CPU cache.
