Very slow start

it is normal that take too long to start atom?
I have files of more than 3000 lines of code and take too long to write code in that file.

I appear much this window

just as I can not write the @ symbol or much less:
you can create another sale by dragging the Pentana outside the editor as well as sublime text?

Have you followed the suggestions in the Debugging document? Also, could you give the following information?

  • Which version of Atom are you using?
  • What OS and version are you running?
  • Can you reproduce the issue after completely exiting Atom and restarting using atom --safe?

I installed atom. The first few times it was starting well and fast but now atom is taking over 20 min to start and I can’t follow the debugging steps because atom is not responding at all. Please help.
