I run it on:
Apple M1 Pro
32 GB
It's weird to me some of the benchmarks like ("filter context fsb") are
reporting 1.67x slowdown, because nothing has changed in the code path (I
expect only filtering bytes and everything using `filter_native` (e.g.
primitives / views) can be affected, but other benchmarks are weird and in my
runs remain the same).
