Yeah, that's what I can see here: fill_prefetch_030,
fill_prefetch_030_ntx are using most of the CPU (about 70 %).
Well, the obvious question is then... any chance we could get an option
to disable the cache? I mean, many of us have been using Aranym for
years for development and it doesn't have any cache whatsoever, so it's
perhaps not much needed for classic development. For counting cycles,
cache misses etc, sure, but that that's when I would enable profiler =
even more slowness anyway.
It's already there : don't use "prefetch / more compatible" nor "cycle
exact" modes. Also don't enable MMU if you don't really need it, as it
has huge impact on performances too.
