2016 Macbook 12" with the M5. Just installed High Sierra last night then did a few hours of work on the machine with lots of windows open, switching apps frequently, etc. It's definitely way smoother. Mission Control is now smooth as butter where before it was annoyingly choppy. I can get info on a folder containing hundreds of large files and the total size and count comes up instantly. Web browsing is very smooth. I have not tried big file operations yet, but I'm sure they will be much better.
This update has breathed new life into my Macbook. Very nice update.
