The stacks in these profiles don't entirely make sense. There are instances of the GC calling back into JIT code in both of them, which never happens.
The first issue I see is that we're doing a lot of minor GCs. Maybe there's another kind of allocation we could pretenure to address this.

All timings are for the JS heavy part of the profile:
2023-02-09 : 8.5 seconds (profile in comment #0)
Bug 1483869 part 12: 8.5seconds -> 6.5seconds
Bug 1823811: 6.5seconds - > 5.3 seconds
and if you enable parallel marking, it shaves off another 0.5 seconds
