Do you find you get 100% across the board on all pages, or even consistently? Because I don’t. Then I ran it through web.dev and got more variation. Jeremy Keith Jeremy Keith

The local browser devtools version? Or the web.dev version? (or both???) Jeremy Keith Jeremy Keith fantastic ms.

I get different results on a different URL. (which is what I find hard getting that silly/gaming about 4x100%) Jeremy Keith Jeremy Keith

I believe the tests run from web.dev or PageSpeed (not devtools) might use different locations which can cause different results. @benschwarz will have more information, he’s done copious amount of research on this :) Jeremy Keith Jeremy Keith @rem

It’s actually devtools that I get the greater variation. But I’ve also put that down to background noise (ie. my browser/cpu doing something else that slows down during the perf check) causing small variances. But that’s a gut based guess. Jeremy Keith Jeremy Keith Ben Schwarz fantastic ms.

Also thanks to you, I’ve got an utterly convoluted OTT service worker! :) Though, I’ve managed to get the titles, last visit, urls and publish dates of offline pages without the use of local browser storage 💪 Jeremy Keith Jeremy Keith

…of course :) Jeremy Keith Jeremy Keith

If you background/hide your chrome window (on mac) it’ll drop cpu priority which will really hamper your metrics. How much variance are you talking? Jeremy Keith Jeremy Keith fantastic ms. @rem
