Google Chrome Traffic Shaping?

Recommended Posts

Posted · Original PosterOP

Here is something interesting that happened to me today.  I was watching a Netflix movie, and I wanted to download the latest Debian Linux DVD ISO.  I started the ISO download in Chrome, it got up to a constant 4 MB/s, I switched back to my Netflix tab, and after a couple of minutes of watching I paused it to check my download, it throttled back to ~200 KB/s before reaching 4 MB/s again.  It did this several times as I paused the Netflix movie and switched back to my Downloads tab.  I never heard of Google Chrome actively shaping internet traffic.

Interesting, I can't say I've ever noticed this myself but it makes sense that they would - whatever you're actively doing should take priority over a passive background download.
