I (accidentally ⏤ Homebrew/brew#1041) loaded a very large number of files into SimpleCov, and it got stuck for a very long time. I tracked down the slowness to this method, which gets very slow because it iterates
filenames
for every value oforiginal_result
. Using Ruby's built-inArray#&
makes this much faster.
