And finally last chart from this series: https://spreadsheets.google.com/a/jay-tech.ru/ccc?key=0AhY8lmfkCabTdGZRSGZ0eXg5cWhkV2k1c0Jvd0lvVnc&authkey=CLeK150N#gid=4 Every image was built by separate bitbake run. BB_SCHEDULER="completion". This build type have minimal peak disk usage - 20G for collie and 33G overall maximum. You can compare it with Chart 3 but Chart 3 build was used bitbake 1.10 (Chart 5 was used bb master). I have vmstat data from last build as well but have no time to parse and analyze it right now. -- Yuri Bushmelev _______________________________________________ Openembedded-devel mailing list [email protected] http://lists.linuxtogo.org/cgi-bin/mailman/listinfo/openembedded-devel
