Luu's test results on different computers.
From his testing, Luu discovered that the operating system and the scanning frequency (refresh rate) of the monitor significantly affected the speed of the computer's response.
For example, the frequency of scanning and displaying characters on the 24Hz screen Haswell-e processor takes 140ms, while on the 165Hz screen is 50ms.
With the operating system, new versions need to take multiple steps to enter a character. For example, with iOS, when pressing a character on the iPad, it needs to go through 11 steps.
Not only in iOS, all operating systems must support a wide range of devices. This makes Android devices Luu tested slower than iOS, and operating systems like Windows or MacOS X later on the same computer compared to Chrome OS, MacOS 9.
Detailed results of Luu's test on mobile devices.
But the latency of modern computers is not a terrible thing, it's a trade-off. Our computers now do more work than a computer 30 years ago even though they have higher latency.
