Not quite, if speed is an issue you consider from start for
algorithmic efficience. Like log(n) instead n, etc. But all fine
tuning should be done after profiling. I can tell from several of my
projects, the actual profile came to a hugh surprise to me, instead of
the places I tried to optimize when coding. As the famous example
code, if the majority of your code only uses 5% of the total runtime,
even if you super-optimize it to zero, the total impact will be
minimal. More often than not, for me the actual profile turns out some
unimportant sounding routine taking >50% of time. And if you
concentrate all your energy on that routine, the impact will be heavy.
