A few things here

  1. Only do frees and memory reclamation out of turns. That should cut a lot of time down when dealing with huge lists that are freed.
  2. Mimalloc can set aside a chunk of memory for heaps. Have it do so per actor to keep their cache better.
  3. Miamalloc can be further optimized by declaring that an object is "small", which is < 1KB. Most JS objects are.
