[Orgmode] [babel] python session speed vs non session

[Seth Burleigh]

I have recently been trying out the src executing capabilities of orgmode. I have been confused why a python session takes significantly longer to execute than a non python session. For example

#+begin_src python

return 2+2

#+end_src

executes pretty quickly, but

#+begin_src python :session test

2+2

#+end_src

executes twice as long. Looking at the command shell for python, it seems that the time is being taken to actually send the source to the command shell buffer. Once its sent (or once i can see it displayed in the command shell buffer) it immediately returns. Any ideas?
