  >windows def allocator is pos Wow, still? I remember allocator benchmarks from 10-15 years ago where there were some notable differences between allocators... and then Windows with like 20% the performance of everything else!

    It’s improved considerably since.

    malloc in uCRT just calls HeapAlloc, though? You can see the code in ucrt\heap\malloc_base.cpp if you have the Windows SDK installed. Programs can opt in to the _segment_ heap in their manifest, but it’s not necessarily any faster.
