The following is from during a www/chromium build attempt after the perquisites have built --so only builder 1 is active. (The context happens to be ZFS in case that matters.)

For example the 2+ GiBytes for 08/ and the long list of 1+ GiByte tmpfs's (smaller than 2 GiBytes in the above). Similar sizable totals happen for "wrkdir" being included (but not using all). (This context had 32 FreeBSD "cpus" and, so, 32 builders.) Knowing this might help folks set up more reasonable configuration settings as far as resource management goes. (So would knowing that various large ports end up with 20+ GiBytes in just their wrkdir .) === Mark Millard marklmi at yahoo.com ( dsl-only.net went away in early 2018-Mar)
