Restarting Solr won't clear the disk cache. When I'm doing perf testing, I'll sometimes run this on the server before each test to clear out the disk cache:

I have a very simple question. Does restarting SOLR removes all caches (including disk caches if any?). I have disabled all caches in solrconfig.xml but even then I see that there is some caching happening all the time. I am currently doing some performance testing and I dont want cache to play any role now..
