The edata_cache_small had a fill/flush heuristic. In retrospect, this was a premature optimization; more testing indicates that an unbounded cache is effectively fine here, and moreover we spend a nontrivial amount of time doing unnecessary filling/flushing. As the HPA takes on a larger and larger fraction of all allocations, any theoretical differences in allocation patterns should shrink. The HPA is more efficient with its metadata in general, so it still comes out ahead on metadata usage anyways. |
