I'm all for dynamic / and dynamic /bin/sh, but this doesn't even come close to what I observed on my systems. I see anywhere from 15% to 20% slowdown in buildworld, depending on how bad my hardware already is. I posted my most recent numbers earlier. It's difficult to get lots of these numbers, unfortunately, because it takes a good 6-8 hours just to complete one build. But the numbers are fairly consistant across the different degrees of old crappy hardware I have. -Mike --WHz+neNWvhIGAO8A Content-Type: application/pgp-signature Content-Disposition: inline -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.2.3 (FreeBSD) iD8DBQE/xDmCCczNhKRsh48RAm5vAKDEv0AVOdckj0NSdw+y2eaY4bMczwCfRFQR KIoRtUJOEIeMSkOt70qICos= =l9Eo -----END PGP SIGNATURE----- --WHz+neNWvhIGAO8A--
