>Custom allocators have the disadvantage of not knowing how the rest of the heap is managed. Sure, but they can work out of a fixed region statically allocated on startup. >Feel free to examine the many papers put out by Emery Berger on the subject of memory allocation as well as the design documents of jemalloc. https://people.cs.umass.edu/~emery/pubs/berger-oopsla2002.pdf https://people.cs.umass.edu/~emery/pubs/berger-oopsla2002.pd... Do you have links to more? I only found one paper from 14 years ago. It is interesting but it comes with a huge YMMV since they only examined specific projects which might not have a pattern that _requires_ a custom strategy anyway. A distribution of the objects along with time distribution would have been nice to include.
