If anyone is Not sure this is relevant, but r326343 is able to run a j4 buildworld to completion on an RPi3 with 3 gigs of microSD-based swap. There are periods of seeming distress at times (lots of swread, pfault state in top along with high %idle) in top, but the compilation completes. In contrast, r328953 could not complete buildworld using -j4. Buildworld would stop, usually reporting c++ killed, apparently for want of swap, even though swap usage never exceeded about 30% accoring to top. The machine employs UFS filesystems, the kernel config can be seen at http://www.zefox.net/~fbsd/rpi3/kernel_config/ZEFOX Thanks for reading, I hope it's useful. bob prohaska
