Yes, sorry, a couple of people pointed that out to me privately. And I did get that mixed up; I was assuming processors, despite the page specifically pointing out "physical cores". I still think there's something to be kept in mind here, though. Even with 4 processors (2 hyperthreaded cores o

I don't believe these counts take into account the number of usage hours of each client, so people with 4+ cores may actually account for a larger amount of relative Firefox usage than their absolute numbers would suggest. I am sure some people on the data / analyst / product side of Firefox

That page says "physical cores", so its not taking into account hyper threading, right? So even a high end macbook pro falls in that category? On Tue, Mar 27, 2018 at 5:02 PM, Mike Conley wrote: > Thanks for drawing attention to this, sfink. > > This is likely to become more important as we con

Are these actual "physical cores", or is this "hardware threads"? There's very big difference between 2 and 2+HT these days. On Tue, Mar 27, 2018 at 2:02 PM, Mike Conley wrote: > Thanks for drawing attention to this, sfink. > > This is likely to become more important as we continue to scale up ou

Just noting that there's bug 1399962 right now -- and if you're single core (like a large portion of very affordable PCs in the past two years or so), the problem can be so bad (bug 1431835) that common sites like amazon can turn Firefox into a not viable option. -- David Durst [:ddurst] On Tue,
