I would be interested to know how E-UAE and integrated AmigaOS4 emulation compare in speed!?
OS4 Interpreted emulated programs, often get boost from OS4 system functions, you hardly notice that programs are emulated, because the GUI, SOUND, DATATYPES and every thing else is running as PowerPC native assembler code.
E-UAE ties to mimic a Classic Amiga, and there for tries to time every thing correctly, AGA, PAULA, CIA, Copper and bitter every thing needs to be emulated, and all this eats up CPU clock cycles like crazy, there is number of setting you can play whit get E-UAE running faster, quality reduction for audio for example, and many other settings.
OS4 JIT emulation is almost as having PowerPC native executables, 680x0 Machine code basically gets translated to PowerPC Machine code, the JIT generated code is not as optimized as PowerPC code generated by a C compiler like GCC, because the CPU flags and Data and Address registers need to be emulated correctly, so deepening on the code your tying to emulate you get different results.
