Extremely slow start up on Windows

See original GitHub issue

yarn rw dev on my Dell XPS 15 9550 (16 GB ram) running Windows 10 is extremely slow. Other Windows users seems to be reporting similar problems on our Discord server.

So I added some timing logs to the dev cli command, and this is what I got

dev.js::handler() base time Sun, 19 Jul 2020 00:04:27 GMT
DB startup. Delta: 0.003 sec
Shutting down "api" side. Delta: 0.066 sec
Shutting down "web" side. Delta: 100.539 sec
Starting everything. Delta: 693.201 sec

dev.js::handler() base time Sun, 19 Jul 2020 00:26:20 GMT
DB startup. Delta: 0.002 sec 
Shutting down "api" side. Delta: 0.068 sec
Shutting down "web" side. Delta: 146.419 sec
Starting everything. Delta: 392.674 sec

dev.js::handler() base time Sun, 19 Jul 2020 00:34:38 GMT
DB startup. Delta: 0.003 sec
Shutting down "api" side. Delta: 0.076 sec
Shutting down "web" side. Delta: 579.419 sec
Starting everything. Delta: 1253.326 sec

Clearly what’s taking time is shutting down stuff. Actually starting the dev server only takes 3 - 4 seconds (timing not shown above). That last one in particular is horrible, with 21 minutes to just shutting everything down. I almost gave up several times, thinking it had crashed or frozen.

So the question then becomes, how do we make it shut down stuff faster, not how do we make it start faster.
