If only it was built using .NET and WinUI, chances are it would've not been so slow (though I did hear complaints about WinUI not prioritizing .NET enough...lots of C++-only mindshare there, and Windows teams have been decimated many times by all kinds of restructuring from what I heard anyways, not expecting much) Also a fun one: There are two cloud drive clients, one uses WinUI and is snappy using ~100MiB of RAM, another one is written with React Native and uses ~250MiB of RAM. Which one is written by Apple and which one by Microsoft?
