Some "manual copy & paste" data from the past (original post is from 2008, repost from 11/2015): *** quote *** FreeBSD 5 on Pentium 4 with 2 GHz and 1 GB RAM: b.world+b.kern: 17494.415u 2562.134s 5:46:42.25 96.4% (with CFLAGS) 17474.169u 2481.368s 5:46:30.40 95.9% (without CLFAGS) 5608.712u 1595.130s 2:13:18.67 90.0% 6382.185u 1788.433s 2:26:36.06 92.8% buildworld: 5086.993u 1431.086s 1:58:16.33 91.8% 11457.047u 2151.158s 3:54:15.31 96.8% buildkernel 2326.380u 234.457s 43:42.15 97.6% 1102.491u 278.194s 25:18.58 90.9% 1182.203u 294.622s 26:12.71 93.9% 1518.402u 310.741s 34:16.96 88.9% 3289.368u 529.669s 1:05:25.90 97.2% installkernel: 5.718u 6.898s 0:30.97 40.6% 6.655u 7.389s 0:32.08 43.7% 6.994u 7.734s 0:33.19 44.3% (...software advance happens here...)

It would be nice if the build system would automatically issue a log file or at least log message about build time and usage statistics. If it wouldn't tell about my brain's age, I would politely ask to have a "flower box"... ;-) -- Polytropon Magdeburg, Germany Happy FreeBSD user since 4.0 Andra moi ennepe, Mousa, ...Received on Tue Jan 17 2017 - 03:09:10 UTC
