I read a lot of speeding up the browser widget, but nothing seemed to help me.
As long i have it closed QGIS 3 is fast but if I open it all actions slows down.
My project is on a local ssd - fast dir scan is enabled on all devices.
What can I do?
I had the same problem. I fixed it by opening the Browse Widget, right clicking on drives I don't need to access and clicking "hide from browser". In my case that included the C: D: (DVD drive), and Y: (my recovery drive sector), leaving everything else as is. Because of the lengthy delay problem, it will take a bit of time. Once all the unneeded drives were hidden, the browser didn't bog anything down. Sorry I don't have an explanation for this behavior.
