Speed tests
Philip Rhoades
I have talked to people here before about speeding up my population
genetics scripts and have made a bit of progress with optimising etc but
I thought I would compare the three versions of Ruby I have been looking
at - NB these results are on my real (not test) code, albeit on a
reduced number of iterations.
I ran the normal number of the inner two loops and only one of the
outermost loop (ie 1/50th of the total) and got the following with the
different versions of Ruby:
ruby-1.8.7-p334 [ x86_64 ] = 31.41
ruby-1.9.2-p180 [ x86_64 ] = 19.53
rbx-head [ ] = 128.42
I realise that rbx started as an interesting exercise but the general
goal would to be eventually faster than v1.9? - if so, it seems like
there is way to go yet?
Regards,
Phil.

I can't say anything about these numbers because I don't know what was being run or how it was being run. For most tight code, rbx is faster so it makes me wonder what you're benchmarking.
Also, you've included no units on your numbers. Are those seconds? milliseconds? microseconds? rbx has to warmup to get good performance, so that matters.
So could you please tell us:
1) what the units are
2) how you got these numbers
3) what the code was that was run
