(Co-founder) well we are/aren't trying to prematurely optimize. It's more like 4 great languages to choose (depending on option) and we don't really know enough to pick and learn one. So we're polling to find out if there is really something that we should with a few requirements. Like we care more about how fast the code runs than the speed of coding.But generally not to the excess of writing in C (etc).

In my opinion, Python, Ruby or Perl are all good choices. You can get things done quickly in PHP, but I would recommend staying away from it as a first language.

Honestly, if you care about speed as much as you say you do, you should be looking into Java. (Or Lisp, if you're not worried about hiring any time soon).
