I totally did not expect this!

GCC and G++ are the fastest. That's the norm.
Java7 faster than Haskell and Fortran. WTF?
LispSBCL and SmalltalkVW faster than Python 3. Jesus Christ.

I hate all these stupid speed benchmarks that pay no attention to memory usage at all. Of course you can unroll the fuck out of all the loops and pad liberally with 64-byte alignment but then you're making a huge sacrifice in size. They should use efficiency metrics like speed/size to compare.

99% of code does not need to be optimized for speed, and should be optimized for size instead.
