Question for Developer Rated 5 out of 5 stars

It feels like after a tab has been unloaded if you click it again it fetches page element again from the web and not the cache i.e. there is a delay of second or two. This was not the case before Bartab Heavy. Is it beacuse page is reloaded liek ctrl+f5 or beacuse the page is loaded into the browser memory cache?

If yes does this pref effect it ~ browser.cache.check_doc_frequency

Any info is appreciated. Also the addon is life-saver. Before FF memory usage easily averaged 1.5gb now it hovers around 500mb mark.
