Overview

Experiment for adding a precomputed cache for zero'd out pages when they're allocated.

clabby commented 12 months ago

This yielded subpar results, probably due to the overhead of having to invalidate part of the tree upon allocation. In the few benchmarks I did, we get a somewhat frequent drag towards the lower end, but it's not consistent across 5-6 runs.

Blue = w/ default cache, red = w/o default cache
