Sorry, part of this paragraph was missing: > Using this, it's possible to see trends in performance. For example, this file: http://drdr.racket-lang.org/23474/collects/tests/drracket/hangman.rkt sometimes times out (the big spikes) and sometimes completes quite quickly. This shows the time to run 'make install': http://drdr.racket-lang.org/23367/src/build/make-install . We can see that Matthew's change to the module cache made installation run about a minute faster. -- sam th sa...@ccs.neu.edu _________________________________________________ For list-related administrative tasks: http://lists.racket-lang.org/listinfo/dev
