For anyone interested, Boost regression tests fare pretty well on the $45 Beagle Bone Black (beaglebone.org). Stop by the release regression matrix and check it out (http://www.boost.org/development/tests/release/developer/summary.html). And while you're over there, investigate & fix a regression test failure on your platform: submit a patch and make the matrix a greener place! (See http://www.boost.org/development/bugs.html.)
