It's worth noting that Chrome has a Device Emulation feature, which allows you to throttle connection speed to common presets such as EDGE/2G/3G/etc. It makes testing mobile layouts easier, at the least.

Also, Mac OS and iOS have the Network Link Conditioner, which can do the same thing (from a network perspective) at the system level:

And Windows, of course, has Fiddler:

And for completeness, Linux has tc [1].

Practically speaking, wondershaper is way simpler for basic throttling.

Maybe it's just me, but aren't the presets on Chrome extraordinarily over-optimistic?

For example, I cannot comprehend how you could get anywhere close to 250KB/s on 2G (which is approx. 2Mbit/s). Furthermore, most WiFi connections cannot get anywhere near 30MB/s (which is 240 Mbit/s).

Either that, or the UI is incorrectly using KB/s when they mean Kb/s (Kbit/s).

I used this at work today. Someone had asked what our webapp's sysreqs were. I said that network connection was very unlikely to be a problem, but it really struggled when set to GPRS. Now, I think it's unlikely that anybody would be using it on that, but it's still good to know that it's an issue.

I would guess that the majority of Facebook's mobile traffic is through their app.
