I did some experiments with different versions of lbm:

- SPEC2021: didn't observe performance regression (three variants: with hht, with hht but disable it via env, and w/o hht)
- Ron's reproducer: observed performance regression if running with `numactl --localalloc --physcpubind=0-xxx`. In this case, disabling it via env can help. If running w/o `numactl`, almost no performance difference. (unclear the tiny difference is noise or not)

All run 10 times.
