WinUAE may be the best Amiga emulator but since all the software worth having on Amiga is designed around a decade of design kludges that never were fixed, it will probably be best to have the real hardware to run the software with.
What do you mean ? Are you saying WinUAE can't run all the software worth having?
(Not to mention WinUAE and FS-UAE are single-threaded emulators.)
That is largely irrelevant, nearly all emulators are single threaded. Communicating between threads is too slow to be of any practical use.
If you were emulating an accelerator you could push that to another thread with it's own fast ram that only it could access and then sync to the other thread when any motherboard access is required. This would mimic what happens on real hardware and possibly could get faster speeds for 68060.
But on a modern PC you can already run faster than any real 68060 ever could, so it's uncertain if the effort is worth it.
The maximum increase would likely only be what the blitter/copper/etc takes to emulate, which is going to be only be a very small percentage. The speed decrease could outweigh that if software was doing a lot of chipram access.
