STR: Go to yahoo.com with netmonitor open Scroll around to cause more content to load It seems like every time there's a request that comes in, we reset the total size to 0kb and wait for a throttle to not receive any requests for a second or two before calculating and displaying the total size, so we get a lot of flashing (as it goes back to 0kb and 0s when incrementing the request count). With a size that keeps loading content like this, the values are distracting with the flashing and the total size and seconds aren't really useful. Probably related, at some point the counter seems to reset itself. In the beginning, there was 2.2mb of content. By the time 153 requests come in, we're back at 62kb, leaving me not really trusting it altogether.
