There is a great comparison between various terminals' latency https://danluu.com/term-latency/ https://danluu.com/term-latency/ (it comes up periodically on HN too - https://news.ycombinator.com/item?id=19443076 https://news.ycombinator.com/item?id=19443076), so once when I was curious if it was just me or if RDP was indeed slower, I did a quick test using the same toolset - https://github.com/pavelfatin/typometer https://github.com/pavelfatin/typometer
It is not a super-scientific test since:
0) I didn't spend too much time on this
1) I wasn't able to test Sublime Text or VSCode over RDP as the tool would stop "typing" after a few characters
2) I did test Visual Studio 2022 though - since this is the primary reason of why I even have a remote Windows box
3) When running on M1 mac, Java can't seem to use native APIs for screen capture, so I'm not sure how much that affects the results
Parameters:
1) Remote - Windows 11, hard-wired LAN, running in 4K using an HDMI emulator plug
2) Local - MacBook Pro M1 Max, over wifi (speed test around 400mbps)
3) Using the official RDP mac app
4) Using Retina mode, True color when connecting (essentially making a 4K HIDPI connection, just checked right now using https://whatismyviewport.com/ https://whatismyviewport.com/ - Chrome gives 2560x1339px screen size with DPR 2.0)
Testing typometer on local (Mac's) Sublime Text:
Average latency: 20.9ms, SD 16.7ms
Typometer running on the remote box itself, Sublime Text:
Average: 51.7ms, SD 39.8ms
Running on the remote box, testing Visual Studio 2022:
Average: 62.7ms, SD 10.2ms
And finally running VS2022 over RDP:
Average: 216.9ms, SD 106.1ms
So overall it is not VERY bad, but it is still very noticeable. For example, autocomplete/suggestions popups feel definitely laggy

- 2Gkashmiri 4y agohey... thanks for typometer. i tested it on the main "computer" running win10 itself running notepad. that gave me avg: 16.2 ms max:18,8 min:14.9 while i set up krdc to use rdp over "wifi" within the same network and i got the result avg:33.9 ms max:75.8 min:29 the max and min are a lot but not in the 200 range. i will confirm again by testing it over zerotier today from a remote location but i don't think it would be as bad.
