A type of compiling that supposedly makes the program that is compiled run faster.

A slightly more detailed response would be a CPU emulation core that will take the 68K instructions and dynamically recompile them to x86 code (and remember their x86 translated form for future use). This theoretically will make the execution slower the first time around, since it's got more to do, but subsequent calls to those recompiled instructions will execute far more quickly. In the case of Basilisk II, I've noticed a precipitous increase in GUI responsiveness and boot times. Simple, repetitive, CPU intensive things also get a really nice boost. Too bad the JIT version of Basilisk needs to be crashed in order to display properly on my system. Oh well. It's just a toy anyway.
