Actually I was quite surprised that multiple queries benchmark showed more than 1 entry for PHP in top 10. take-away: if you don't do much sophisticated data processing then PHP is ok choice. gets ready to run

That's because php is a really thin wrapper around the underlying C libraries. The thing that makes it ugly is what makes it fast. Php is still interpreted and not jit'ed, even with the opcode cache used in this benchmark, so it loses out in anything that exercises the php code side of the equation, which is why the big php frameworks (symfony, cake and laravel) are 50 times slower than raw php. I wonder how facebook's hhvm engine would stack up, as it is a jit'ing php engine and supposedly an order of magnitude faster.

  That's my understanding of the situation as well. As a related aside, we have an intention to eventually capture some additional statistics about the implementations such as source lines of code, total number of commits, and possibly lines of code of libraries (where available). These are just additional data points to use as the reader sees fit, but they may provide some insights. For example: (a) developer efficiency, assuming you are comfortable using sloc as a proxy for developer efficiency, which is admittedly a hotly debated matter; (b) commits are a proxy for the level of attention the particular test implementation has received in our project, since a test with only 1 commit may be unrefined and in need of tuning and a test with dozens of commits may be considered highly volatile; (c) where applicable, the performance impact of additional code, perhaps even as granular as a calculated average per-line cost in rps. The last point might be particularly illuminating for languages such as PHP.
