Python Watchdog PollingObserverVFS Повышение производительности

Я запускаю PollingObserverVFS в каталоге, который находится в хранилище Dell ISILON Storage с более чем 2 миллионами файлов, и для обнаружения изменений требуется около 2 часов 30 минут. Есть ли способ повысить производительность, чтобы быстрее обнаруживать изменения, такие как параллельная обработка или любые другие изменения настроек.

Код объединяет хранилище Dell Isilon для обнаружения изменений папок.
