I have only 32GB mem, but AWS has larger memory machine! Linux perf shows here is bottleneck: https://github.com/python/cpython/blob/master/Objects/obmalloc.c#L1784-L1819
obmalloc sorts arenas by number of free pools. If there are many arenas, and memory block is freed by random order, this sorting become O(N^2). That's too bad. I'm trying address order instead.
