Amithlon wasn't so much an Amiga emulator as it didn't actually emulate an Amiga (ie. the custom chips, which to me were what makes an Amiga what it was). Rather it was a way of running Amiga OS 3.x on a x86 machine on top of a barebones linux kernel.
I torrented it several years ago to try out (it wasn't available to buy anymore) and it was very fast. In UAE the customer chip emulation takes 90% of the processor time so the reason Amithlon was so fast is because it didn't bother with any of that, but you had to run hardware-banging apps in E-UAE on top of Amithlon which kinda negated the whole point.
