Hi gurus and nubys,
I was playing with the ruby programs in the alioth language shootout
and I realized I have no idea on how to benchmark them all.
What I mean is: If I want to benchmark a single function I can use the
usual benchmark code also shown in ri, but what if I want to check two
slightly different implementations of a a single program?
I can't just stick them all in a #meth1 and #meth2 thing, since there
may be constants defined (actually they almost surely will, at least
classes and modules), I suppose I could do something like:
Benchmark.bm do |x|
x.report {require 'first_impl'; main()}
x.report {require 'second_impl'; main()}
end
but this seems kludgy and loading the thing at each run could mess up
the results, I think.
Some suggestions, apart from using the time unix utility ?
