(1) Sometimes I notice that the bandwidth goes up a lot after I start getting a large feed. Like, my internet might be going pretty slowly, then I start downloading a large file and my internet connection moves up to 24 or 36 Mbps, loading web pages very fast, despite the fact that I am also downloading a large file in the background. Why? (2) I also sometimes notice a bandwidth increase just from loading a lot of alternate sites. For example, my internet is going slowly, web pages are loading only quite slowly, then I open up a couple of other tabs and alternatively click on google news web pages for 10-20 clicks (separated by 2-3 seconds), and it will increase my connection speed such that web pages start to load faster.... ?
