So interesting to see. Though I think if Cloudflare really wanted to safe more memory, there are even more strategies. Just starting with pointer compression, even if that is not an option, other techniques exist in rust. Assuming some numbers in from the previous post, with 250GB per byte wasted, you could shave off 2bytes of every pointer or 4 if you can fit them into a context related memory cage. And even that is just a beginning here.
