It will take twice or trice longer time when _all_ packages with ELF files will get their set-versioned dependencies, so I expect apt-get startup will eventually be about 10x slower again (compared to 5.1 branch). apt-rpm indeed calls rpmRangesOverlap() too many times, it's common knowledge. Unfortunately, stating this fact isn't sufficient to make apt-rpm work faster. --=20 ldv --W/nzBZO5zC0uMSeA Content-Type: application/pgp-signature Content-Disposition: inline -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.10 (GNU/Linux) iEYEARECAAYFAkz6zjQACgkQfKvmrJ41Nh5tKgCfWRKBS/YqOLSCtiWwcWWKiKj9 lDwAn0tMjdVp5+B8DXBSOqMu18ZiIolX =d5Wa -----END PGP SIGNATURE----- --W/nzBZO5zC0uMSeA--
