Lighthouse Throttling Details

[Monica Lambate]

Hi Team,

We are currently using Lighthouse worker version 6.1.1 

We generate the data for various customer URLs with device type in Desktop & Mobile in 3 profiles i,e  slow, fast, medium.

We are willing to change the throttling configurations.

We have come up with the following configurations 

const throttling = {

//Desktop Fast

desktopFast: {

rttMs: 40,

throughputKbps: 10 * 1024,

cpuSlowdownMultiplier: 1,

requestLatencyMs: 0,

downloadThroughputKbps: 2000,

uploadThroughputKbps: 800,

},

//Desktop Medium

desktopMedium: {

rttMs: 300,

throughputKbps: 10 * 1024,

cpuSlowdownMultiplier: 1,

requestLatencyMs: 0,

downloadThroughputKbps: 1500,

uploadThroughputKbps: 750,

},

//Desktop Slow

desktopSlow: {

rttMs: 1000,

throughputKbps: 10 * 1024,

cpuSlowdownMultiplier: 2,

requestLatencyMs: 0,

downloadThroughputKbps: 600,

uploadThroughputKbps: 300,

},

//Mobile Fast

mobileFast: {

rttMs: 80,

throughputKbps: 1.6 * 1024,

requestLatencyMs: 150,

downloadThroughputKbps: 1.6 * 1024,

uploadThroughputKbps: 750,

cpuSlowdownMultiplier: 2,

},

//Mobile Medium

mobileMedium: {

rttMs: 100,

throughputKbps: 700,

requestLatencyMs: 300,

downloadThroughputKbps: 750,

uploadThroughputKbps: 500,

cpuSlowdownMultiplier: 4,

},

//Mobile Slow

mobileSlow: {

rttMs: 300, 

throughputKbps: 700,

requestLatencyMs: 300,

downloadThroughputKbps: 500,

uploadThroughputKbps: 300,

cpuSlowdownMultiplier: 8,

},

};

Could you please suggest if we are doing it correctly?

Also, could you please also let us know how did you decide on these configurations in your lighthouse project?
