I'm trying to run a long Python code block (~4000 lines) in org mode. The code is sandwiched between: #+begin_src python <python code block> #+end_src
It runs fine, but org mode becomes incredibly slow - when typing text there is about a 10 second delay before the character appears on the screen. If I reduce the number of lines of code in the block there is a noticeable increase in speed. I am not using line numbers, and the delay is not ameliorated by turning off fontification. If I add a semi-colon before #+begin_src, to comment it off (get rid of src environment), then org mode returns to it's normal speed. Do I just have to accept that long code blocks can't be entered into Org Mode? Any help would be appreciated. I am running Org Mode (version 8.2.10) on Windows 8. Thanks Angus M
