On: How fast can the RPython GC allocate?

[yvdriess]

In defense of the OP: bump allocators are part of the CPython runtime. It's used to avoid calling malloc a bazillion times a second. Of course, it still needs to defer to libc for certain objects and to grab more memory for its pools/arena/nursery.

[kragen → yvdriess]

This is about the PyPy runtime, not the CPython runtime.
