We would like to run another experiment for the Network State Partitioning effort to better understand the performance impacts of double-keying (top frame site) vs triple-keying (top frame site and frame site).

I’ve omitted all of the information contained in previous intents that hasn’t changed. Here’s a link to the last (triple-key) I2E.

Blink component


Goals for experimentation

We want to roll this out to 1% of Stable traffic (i.e., this is not an Origin Trial) to be able to compare to the previous experiment.

Estimated milestones

We’d like to run at 1% on Stable for ~1 milestone (ideally in M101 or perhaps 102 depending the timing of a bug fix).

Tracking bug

Launch bug
