Question about localhost:8000

I wanted to be able to switch between projects on my local server. So instead of launching the local server at the project level (02, 03, etc), I launched it at the master project folder level (udemy-d3-master). The problem is that after a while, I noticed everything slowing down a lot, i.e. mouse did not respond immediately, took a really long time to switch between screens etc.

  • Is this slow down due to the change I made in launching local server?
  • Is there a way to avoid the slow-down?
  • Or should I just go back to launching at project level? (And if so, is there another way to be able to easily switch between projects but not have to shut one down then switch to another in command line).
