Avoid overhead of creating a Stream in filterRulesVisitingFragmentSpreads, and instead just do the filtering inline in a for loop.

Did this turn up in a profiler or just getting rid of .stream()s

Hey @bbakerman . I am not trying to get rid of all stream calls, this came up when I was profiling an instrumentation implementation. It is true though that in hot code, stream can add quite a bit of overhead. For trivial scenarios like the filtering done in this method it seems straightforward to just unroll it into a loop and avoid the cost. |
