Did anyone else find it strange that Ruby only beat Python and PHP in the median range? On both ends Python and PHP are both quite faster. I don't really know how to read this thing, but I feel like this title is probably misleading?
When speaking about languages in the same ballpark (Ruby, Python, Perl, etc), it's difficult to make blanket statements about which one is "faster", because they each have their warts. Depending upon what your application needs to do, you may run in to those warts.
