It's not so much your switch as it is your bandwidth and router. Downloading a lot, such as torrents uses all your bandwidth. Having multiple devices on the network taxes your router. The only thing the switch does is split the signal from the router to more devices on your network. It has nothing to do with what you are downloading or what games you play. However, if you have a cheap router, you might face issues. Also, if you have low bandwidth internet service like ATT, then you might also face issues. Best thing to do is cap your download and upload rates to give yourself the bandwidth you need for your other devices.
