title: Python VS code taking too much memory and taking too long to auto complete
body: <p>I am a beginner learning to program python using VS code so my knowledge about both the VS code and the python extension is limited. I am facing two very annoying problems.</p>
  <p>Firstly, when the python extension starts the memory usage of vs code jumps from ~300 mb to 1-1.5 Gbs. If I have any thing else open then everything gets extremely sluggish. This seems to me a bit abnormal. I have tried disabling all other extensions but the memory consumption remains the same. Is there a way (or some settings that I can change to reduce the memory consumption?</p>
  <p>Secondly, the intellisense autocomplete takes quite a bit of time (sometimes 5-10 mins) before it starts to kick in. Also it stops working sometimes completely. Any pointers what could be causing that?</p>
  <p>PS: I am using VS code version 1.50 (September update) and python anaconda 4.8.3.</p>
