Comment #1 on issue 2428 by [email protected]: Regexp is extremely slow http://code.google.com/p/v8/issues/detail?id=2428
That looks like a bad regexp, shouldn't the inner "[\x00-\x7f]+" be written as "[\x00-\x7f]" (ie. without repetition)? Otherwise the inner repetition and outer repetition cause the search space to explode, so I'd expect this to take long.
