Firefox used ~50% less memory than Chrome on open pages, but the composite memory score was slightly for Chrome because after closing the tabs Firefox used more memory over its starting amount. Tom's basically treated this as a leak when really it was just fixed overhead (wouldn't grow when opening and closing the tabs over and over).
FF 'won' this benchmark despite a unfair memory score against it.
Pages that were recently visited are stored in memory in such a way that they don't have to be re-parsed
I guess the same applies for closed tabs, since those can be re-opened as well.
What does Tom think caching is, or what unused RAM is good for? To be a pretty and useless number in the task manager? That not all users understand this is one thing, but a so-called reviewer? Just wow. Thanks for actively making people worse informed, Mr. Expert.
