I recently installed 9.2-RC3. It takes about 47 minutes to do a 'make -j9 buildworld buildkernel' on this machine, but if I do a suspend and resume, it takes much longer to do this same operation after the machine comes back up - for example, it took 1 hour 37 minutes to do the same buildkernel/buildworld after the resume from suspend.
It looks like the 'rm' operations are happening especially slowly - there is not much disk or CPU activity going on when I see 'rm' on the terminal, vs. before the 'zzz', when the disk and/or CPU seem pretty busy most of the time during the build. I know that suspend/resume is a bit flaky, but it's been pretty reliable for me under 9.1. >How-To-Repeat: as root cd /usr/src rm -rf /usr/obj time make -j9 buildworld buildkernel zzz (wake up the box) (repeat the above) >Fix: >Release-Note: >Audit-Trail: >Unformatted: _______________________________________________ freebsd-bugs@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-bugs To unsubscribe, send any mail to "freebsd-bugs-unsubscr...@freebsd.org"
