This can reduce memory fragmentation in long running (server) programs. By setting it to `0` no such page resets will be done which can improve performance for programs that are not long - running. As an alternative, the `MIMALLOC_RESET_DELAY=`<msecs> can be set higher (100ms by default) to make the page + running. As an alternative, the `MIMALLOC_DECOMMIT_DELAY=`<msecs> can be set higher (100ms by default) to make the page reset occur less frequently instead of turning it off completely. - `MIMALLOC_LARGE_OS_PAGES=1`: use large OS pages (2MiB) when available; for some workloads this can significantly improve performance.
