I'd use anything else for the slowness alone if I could decide the tools at work myself.
The best part is that 10 years ago I used to have an absolute piece of dog shit WinCE phone that failed to even keep up with my typing speed in its stock SMS app. Google Maps worked perfectly on that device.
And it is even worse in firefox than in chrome.
It takes 30s to 1 min to load(!).
It has cached last view, which loads fast.. then it goes unresponsive for bloody 30s to 1 min anyways.
3 different machines were used to test this - i5 6th gen laptop, i7 7th gen pc, i7 3rd gen pc - all of them with plenty of ram(at least 16gb).
So they're driving down the time it takes to do what they magically infer I'm trying to do. Is this why whenever I try to organize my gmail box I give up 10 minutes in because the UI is slow and bullshit? Because it's good for metrics that I can't make my gmail account anywhere near as useful as my work email?
Most certainly you could misuse the statistics for blind number worshipping, and I’m sure there are many anecdotes of that kind of behaviour. But I’m also quite certain that successful organizations can use these to improve their products in meaningful ways. I suspect any gmail product manager who tried to slow down their product (or resisted fixes) to improve meaningless time spent metrics would be crucified.
