Currently mtx_pool just uses a simple array (I have patches to force the array members to be cache-aligned, but they haven't been shown to help in any benchmarks to date). I do think though that I would prefer embedding the mutexes in the hash table entries directly. This is what we do for the turnstile and sleep queue hash tables. -- John Baldwin _______________________________________________ freebsd-hackers@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-hackers To unsubscribe, send any mail to "freebsd-hackers-unsubscr...@freebsd.org"
