The distributor in me cried out when I read over this.
I know I am kind
if nitpicking here, but please consider how much nicer this would be if
the small benchmark was run at start up time instead of compilation time.
Its not much more work to compile both algorithms into different object
files and set up a function pointer at startup. And it will
give you best performance even if you move the precompiled binary
from one machine to the other, or if you change the CPU in your
computer without reinstalling.
Mmm right, but in that case the upstream author has to do the compilation for
all kind of architectures ... not even knowing what kind of architectures are
covered by distribution X. Isn't that the "job" of a distribution maintainer
to do such compilation task? ;-)
Besides, a binary distribution has no chance of
knowing the exact
hardware in use on the users side. The configure test will only benchmark
the build host, which is not really useful.
Yeah I know, that's why the benchmarks can be circumvented by configure script
parameters for cross compilation. Somebody has to compile and somebody has to
run the benchmarks ... whoever that will be ... :-)
