After I upgraded to iOS 11 on an iPhone 6, I noticed different forms of performance loss:
- lag to start some applications,
- interface buttons which seems like on slow motion,
- virtual keyboard starting to display the characters I typed after 3 to 4 of them,
- lag in web browsing (but a part of the problem might come from the network interface in use and the load of the connection and the remote server,
Before switching to iOS 12 (which we can test to check), I would like to take advantage of this upgrade to make a correct performance measure of iOS 11 so as to be later able to compare it with the performance of iOS 12.
I would like to measure a number which is network independant and processor independant so as to be able to compare iOS version performance only. Of course an OS performance can’t be fully characterized by a uniq number. For example one OS might be faster on files manipulation, when the other might be faster in graphical interface rendering. But as unperfect as it is, it is always possible to compute a weighted average of performance along different key functions.
I had a look at some great benchmarks like Geekbench but most of them are focused on giving numbers which characterize the processor performance and not the OS one. For example, Geekbanch doesn't provide the iOS version on which the benchmark was run.
Which benchmark would provide a performance “indicator” to characterize the OS helping to compare iOS 11 and iOS 12 performance. Of course on same physical architecture, within the same networking environnment & with the same OS load?
