Pylint uses parallelism to improve performance, but high startup costs means that this only makes sense if there are lots of files to be processed. So, a while ago a change was made such that if there are fewer than ten files to be analyzed then no parallelism is used. Our Pylint wrapper also has a hack where it does one type of check in serial mode, because that is the only time it is reliable. This requires running Pylint twice, which is expensive. If there are a small enough number of files to analyze then we will be doing serial analysis anyway, so there is no need to do two separate runs. In this test case: git cl presubmit -v --files tools\code_coverage\create_js_source_maps\test\create_js_source_maps_test.py the cost of Pylint is dropped roughly in half, from six seconds to three seconds, by eliminating one of the three-second runs.
