Well that blows my theory :) However... in January my system took around SA>4 hours to do 'make world' and it still does with today's code (if I don't SA>have SA>debug options turned on). So I'm not sure there is a global 3x increase. Well, you're the 2nd one who reports that nothing has changed. Several people however report, that they see the 3x increase. And I see it myself, no matter how often I look at this. Today I tried to build the vinum module: gcc-3.3.1 yesterday's kernel 132 + 85 + 20 gcc-3.2.2 yesterday's kernel 131 + 85 + 22 gcc-3.2.2 kernel from June 1st 52 + 27 + 7 Exactly the same config and the same world (except for gcc). This is an Ultra10. Perhaps it depends on the sparc model? harti -- harti brandt, http://www.fokus.fraunhofer.de/research/cc/cats/employees/hartmut.brandt/private brandt@fokus.fraunhofer.de, harti@freebsd.org
