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.
