RSpec and Rails tests are 100% CPU bound

No, the test process doesn't usually peg the CPU. Single threaded database connection usage in the test process is the problem.

Faster rspec: spork & parallel_tests runner. One test process per CPU core, and a preloaded rail environment, test run split across processes.

I suppose I should have said single-core CPU bound, yea.
