From the BFS FAQ (lack of NUMA support causes additional memory latencies,
the high end business server these days have NUMA): NUMA aware? It is NOT NUMA aware in the sense that it does any fancy shit on NUMA, but it will work on NUMA hardware just fine. Only the really big NUMA hardware is likely to suffer in performance, and this is theoretically only, since no one has that sort of hardware to prove it to me, but it seems almost certain. v0.300 onwards have NUMA enhancements.
