title: PyCharm hanging for a long time in iPython console with big data
body: <p>I've seen some reports PyCharm is slow but I'm having an issue that seems that's too slow even compared to normal operation.</p>
  
  <p>I have a big set of data in a pandas dataframe (read from a 440 MB csv file).</p>
  
  <p>When I'm using the ipython console inside PyCharm, every time I try to handle that data, let's say, I write <code>my_data.</code> it just hangs there for about 30 seconds.</p>
  
  <p>I don't really understand what is going on, but it seems PyCharm is going trough all the data to find some smart auto completion (which is a really dumb thing to do).</p>
  
  <p>Any way to deactivate this behavior?</p>
