I have XAMPP running on localhost on Windows 7. I was trying to find a way to simulate the bandwidth of dialup and 3G connections.
Is there a current solution which works on a localhost and Windows 7 and is reasonably straight-forward to enable and disable as necessary?
The easiest way to use Chrome developer tools. On network tab, there is feature to throttle bandwidth in different use cases.
Chales proxy includes a bandwidth throttle.
You can use @sitespeed.io/throttle - an npm package.
Example:
# simulate slow 3g connection on localhost
npx @sitespeed.io/throttle 3gslow --localhost
# throttle localhost with roundtrip time of 200ms
npx @sitespeed.io/throttle --rtt 200 --localhost
# later when you are done,... stop throttling
npx @sitespeed.io/throttle --stop --localhost
Note that throttle requires sudo, and will prompt for user login.
Alternatively, throttle can be used programmatically in NodeJS.
Example (copied from docs):
const throttle = require('@sitespeed.io/throttle');
// Returns a promise
const options = {up: 360, down: 780, rtt: 200};
await throttle.start(options);
// Do your thing and then stop
await throttle.stop();
See the documentation for more options.
