Thank you! I'm still getting inconclusive results. I've googled "Ubuntu – WSL: Am I running version 1 or version 2":
* running "wsl -l -v" in a windows shell gives me: NAME STATE VERSION Ubuntu Running 1 Getting a version number at all is apparently an indication of running WSL2. * running "uname -r" (without options, uname only given back "Linux" which I don't think is distinguishing information) I get 4.4.0-19041-Microsoft I guess 4<19. On the other hand, 4.4 > 4.19, so I'm not sure what that is telling me. In any case: do people get "fair" performance under WSL or WSL2? Does Cygwin give better performance? Is development even possible/convenient under Cygwin? My impression (with both my laptop and the Surface Pro 7 having an intel core i5) was that I should be getting similar performance. On the other hand, the Surface doesn't seem to show any fan action at any point whereas the laptop is quite happy whirring away whenever some load comes its way, so it could just be that the Surface is passively cooled and therefore throttled into computational mediocrity (the surface is really just a tablet to write on and as a tablet OS, win10 seems to be performing just fine). I think the students who'd be using Win10 for development would have beefier machines.
