App has to run slow interpreter/baseline compiler.
Background compilation has a large working set and seriouly competes for LLC.

No, collecting short lived objects is expensive.
Copying is expensive.

VM allocators have no magic over C++ allocators, except that you can't customize.

C++ needs 0 check.
The optimizer usually has to leave some check uneliminated unhoisted.
And even redundant checks is diffcult to eliminate.
