User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_13_2) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/63.0.3239.59 Safari/537.36

Steps to reproduce:

Simulate a bad network with https://blog.nightly.mozilla.org/2016/11/07/simulate-slow-connections-with-the-network-throttling-tool/. Then load an application that loads a lot of data over a websocket and see whether the speed is affected. 


Actual results:

The websocket connection appears to not be throttled. Note that Chrome has a similar limitation: https://bugs.chromium.org/p/chromium/issues/detail?id=423246. 


Expected results:

I'd expect the connection to be limited for websockets as well.

Thanks for filing!  You are correct that WebSockets is not throttled yet.

At the moment, we can only throttle things that are observable to our network monitor, and at the moment, WebSockets are not shown there.

I'll mark this as depending on basic WebSocket support in DevTools.

Now that WebSocket support is in DevTools, is this unblocked?

I'll investigate.

Moving this over to Honza, now that it's clear this isn't an RDM issue.
