It is on anything less than 384MB even with kern.cam.ctl.disable=1 here, being on a thinkpad T23, 1133MHz P3-M on 9.1-R sources. At 256MB - the minimum earlier that completed installation without disabling CTL - swap often sat at ~14MB but blew out to around 165MB building those huge llvm libraries - cc1plus 332M, 173M resident was one top I snipped, but I can't say I caught the biggest. I let it finish anyway: 7h40m! When I ran buildworld again (as before, straight, no arguments) after removing /usr/obj and adding WITHOUT_CLANG=yes to /etc/src.conf (thanks Glen), I expected big savings but was surprised when it ran just 3h32m. Then I added 128MB (to 384MB) and repeated the first buildworld (incl. clang) expecting huge savings as it'd only touched swap to about 12MB a time or two, mostly having 100MB+ of free memory .. wow, down to 7h02m! Here at least, building llvm libs and clang doubles buildworld time! and extends /usr/obj from 675MB to 1GB. > To the buildbox! When I take it back to 768MB, that'll be my buildbox! :) cheers, Ian _______________________________________________ freebsd-stable@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to "freebsd-stable-unsubscr...@freebsd.org"
