[PATCH] D122922: [lld][common][lld-macho][lld-coff] Support per-thread allocators and StringSavers

[Jez Ng via Phabricator via llvm-commits]

int3 added a comment.

> We did experimented with using a modern/threadsafe allocator here, specifically tcmalloc internally at google and found that it was pretty good (ie., no slower than the bump-ptr alloc). But conceptually the bump-alloc could be faster in simple cases so we thought it wouldn't hurt to use both when possible. (ie., have a thread safe bump allocator and a fast system malloc).

IIRC you found that tcmalloc-for-everything was at parity with bump ptr alloc + system allocator, but bump ptr allocator + tcmalloc together was still faster than tcmalloc-for-everything, right?
