Change Details

Considering map->anon_loc as a stable address for searching unallocated regions allows for better reuse of returned memory regions. Continuously updating map->anon_loc could impact jemalloc metadata consumption when handling virtual address upward shifts. By stabilizing the address of map->anon_loc, we can mitigate metadata consumption in jemalloc.

introduce `vm.anon_low_pref` option to optimize cluster anon behavior. Enabling this option, will stabilize `map->anon_loc` for searching clustering candidates allows better reuse of returned memory regions. This option is disabled by default. Continuously updating map->anon_loc could impact jemalloc metadata consumption when handling virtual address upward shifts. By stabilizing the address of map->anon_loc, we can mitigate metadata consumption in jemalloc.
