After trying a bunch of different features, it appears to me that attaching USB drives to the router causes the greatest memory increase, especially for two drives. But as others have said, high RAM usage appears to be typical and not an issue. I see no difference in performance when RAM is fully utilized as indicated in the WebUI.
I think as long as you have enough swap, it's ok.. As to the RAM usage increasing with the USB drives it must be the file buffers/cache.
