The good news is if nothing is > defined, it does the right thing. The idea is that the default is to *not* bootstrap the compiler, if the system compiler is new enough. E.g. if you build r350256 from a system built before r350256, it will normally automatically bootstrap everything. E.g., your previous builds did not have to bootstrap, and now they do, which is why they take longer. So the only good way to compare is to force MK_SYSTEM_COMPILER=yes and MK_SYSTEM_LINKER=yes, so both buildworlds will do the same thing. I did a few tests on a relatively fast machine, and buildworld with those settings on took approximately the same time at r350255 and r350256. I'm now repeating those experiments to feed the results to ministat. -Dimitry --Apple-Mail=_505C1569-AB6B-45EF-BF74-58E3B3385237 Content-Transfer-Encoding: 7bit Content-Disposition: attachment; filename=signature.asc Content-Type: application/pgp-signature; name=signature.asc Content-Description: Message signed with OpenPGP -----BEGIN PGP SIGNATURE----- Version: GnuPG/MacGPG2 v2.2 iF0EARECAB0WIQR6tGLSzjX8bUI5T82wXqMKLiCWowUCXTjLxAAKCRCwXqMKLiCW o5eJAJ9AzKo5AkgsIusI2vHzbXqcCEw20wCgir2Ow1kFNRpR2MZsiN+Lo1MajB4= =T8cf -----END PGP SIGNATURE----- --Apple-Mail=_505C1569-AB6B-45EF-BF74-58E3B3385237--
