If speed is that important, you should NOT be worried about wasting your
time re-writing the code. You should be worried about wasting your time
speeding up code before you know whether or not it's slow. You should be
worried about wasting your time correcting bugs that you introduced by
making it more complicated than it needed to be, before you've collected
enough information to justify concluding that it needed to be that
complicated.
You should be worried about wasting your time speeding up a part of the
program that contributes little or nothing to the total run time, time
you could have spent speeding up the part of the program that really
runs slow.
Write it readable, write it correct, run it to determine whether it's
fast enough. If it isn't, profile it to identify time hogs - and only
then, start re-designing the time hogs (and only the time hogs) for
improved speed. Designing for speed at any time prior to that is likely
to produce a speed improvement too small to justify the time spent to
achieve it. You can cost-effectively apply your time to speeding up your
program only if you first have a program to speed up, and measure it's
speed to determine which parts deserve your attention. Those usually
aren't the parts you thought would need your attention.

Making that decision based upon speed, before you've got any code to
measure the speed, will be a bigger waste of your programming time.
