Without clicking the link i knew this was going to be Jeff Atwood - something about iPhone's JS performance seems to crack him up perpetually! :) Also see Dan Kaminsky's reply -
"I took a quick look at Speedometer 2.0 and it seemed to be driven by the speed of the browser cache implementation, as in how much was explicitly in memory, what poked the file system, how async was implemented. Not CPU bound."
- xrd 8y agoThat's pretty serious, right? Changes the entire conversation if this is not truly improving execution speed?
- blinkingled 8y agoYes - and if it does it doesn't matter for this particular benchmark which isn't CPU bound.
- codinghorror 8y agoJS perf has tightly tracked single threaded CPU perf for a long, long time -- as long as I can remember. That said, it is certainly possible memory speed is also a factor, see https://www.anandtech.com/show/13392/the-iphone-xs-xs-max-review-unveiling-the-silicon-secrets/3 https://www.anandtech.com/show/13392/the-iphone-xs-xs-max-re...
