Perceived sluggishness in the desktop response. Perhaps it's my memory or imagination but I remember that dos/win3.11 had an almost immediate desktop and application response on a pentium. I'm sure with a lightweight linux I can approach the speedyness and MacOS on an M1/M2 has a good enough desktop response.

I turn off animations in win10, makes everything much snappier feeling.

It's not just you - we went from "render when ready" to "start an animation of a fixed duration when ready". At least, that's one of the issues I've found.

BeOS was magically snappy and responsive on 7200RPM spinning rust with a single-core 166Mhz Pentium and 128MB of memory. Felt luxuriously powerful. The only widespread current OS that's even close to that level of responsiveness and good-use-of-resources is iOS, and it's been slipping for years such that I now hesitate to make the comparison. And it gets there largely by cheating (suspending backgrounded programs).

The USB 2.0 stack has higher latency than the PS/2 stack – but that's no excuse for the sheer lagginess of the OS. Ooh, just learnt that USB 3 fixes this problem! Never mind.

  USB 2.0 has a theoretical minimum latency of 125us. PS/2 has a theoretical minimum latency of 659us, because the maximum serial clock is 16.7kHz, and the smallest scancode is 11 bits. This ignores considerations of matrix scan rate, debouncing, key travel distance, key activation point, the fact that many PS/2 scancodes are bigger than 11 bits, and the fact that USB can transmit more than one key at a time. rtings.com measures the keyboard I'm using at 0.5ms latency[0]. I'm confident this is faster than any PS/2 keyboard. [0] https://www.rtings.com/keyboard/reviews/razer/huntsman-v2 https://www.rtings.com/keyboard/reviews/razer/huntsman-v2
