Since > having 100 files in 160 directories would not have the same impact, right? @magicus so the first test I did was 16,000 files in multiple directories, as I thought that was more representative, and would involve multiple small sorts vs one large sort. I have just re-run the tests again, for both 16000 multi-dir and 16000 single dir, and the results are similar: 16000 multi-dir x50: Existing code: 291 seconds (variance: +/- 3 seconds) New patch: 293 seconds (variance: +/- 3 seconds) 16000 single-dir x50: Existing code: 235 seconds (variance: +/- 3 seconds) New patch: 237 seconds (variance: +/- 3 seconds) ------------- PR: https://git.openjdk.java.net/jdk/pull/6395
