ーーー
So what happened was that compiler vendors modified their compilers to specifically detect that they were compiling 179.art, and applied these specific changes.
Sun was probably the first to do so, but eventually such optimizations became widespread, with performance gains of 30 times or more common.
The optimizations were in no sense general-purpose: they accelerated 179.art, but would not increase the performance of any other piece of code on the planet.
