However, last I looked there Neil was still using 4 KiB obmalloc pools, all page-aligned. But using much larger arenas (16 MiB, 16 times bigger than my branch, and 64 times bigger than Python currently uses).
I was testing it verses your obmalloc-big-pool branch and trying to make it a fair comparision. You are correct: 4 KiB pools and 16 MiB arenas. Maybe I should test with 16 KiB pools and 16 MiB arenas. That seems a more optimized setting for current machines and workloads.
