--hQiwHBbRI9kgIhsi Content-Type: text/plain; charset=us-ascii Content-Disposition: inline Content-Transfer-Encoding: quoted-printable I recently ran "make delete-old" on a -current box and felt it was rather slow. That prompted me to do some more careful experiments. On one box where I have both 8-stable and 9-stable available, there was a ~30x slowdown (based on 5 runs, ignoring the first). I don't have a -current world on that box so I can't directly compare but on another pair of fairly similar boxes, I get a ~180x slowdown between 8-stable and -current (and that figure is probably optimistic since the -current box was idle whereas the 8-stable box was fairly busy). I realise that "make delete-old" isn't something you nede to do every day but going from sub-second to multi-minute duration is quite noticable. Can anyone suggest what has caused the change? --=20 Peter Jeremy --hQiwHBbRI9kgIhsi Content-Type: application/pgp-signature -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.19 (FreeBSD) iEYEARECAAYFAk+0MucACgkQ/opHv/APuIeudgCfcizw5gqvdpbLmDYa/Dv3uhfV rnkAoIHZjs2Y8gB5q5iElLTBlqTjxAPE =ZttN -----END PGP SIGNATURE----- --hQiwHBbRI9kgIhsi--
