I certainly hope it hasn't become that much slower, because > my sparc is slower than yours! It's definitely longer. On an Ultra 5 my buildworld time is now 1068m1.246s and my buildkernel is 442m44.184s. Add those together and you get more than 25 hours. Relevent CPU details: cpu0: Sun Microsystems UltraSparc-IIi Processor (360.00 MHz CPU) (I beleive the version of the UltraSparc 360 in the Ultra 5 has the 256K of cache rather than the 2M ... anyone know of a way to probe that from within FreeBSD? `dmesg` doesn't seem to show it.) I used to be able to start `make buildkernel && make -j4 buildworld` before going to work and have it done by the time I got home, so figure that at under 10 hours. I don't know for sure how long it took - it was short enough that I didn't see any point in timing it :-) The recent problems where -jX wouldn't work on buildworld have also had an additive (though small) impact on the times, roughly two hours in my case (slow drives, heh). I haven't had a chance to try a -jX buildworld recently to see if they're working again (note that the times I gave are from when they were working). On the other hand, I haven't had /any/ problems with the new gcc (extra warnings about inlining excepted), which is a good thing. -T -- Happiness is wanting what you get, NOT getting what you want. - Robert Heinlein
