How to improve when Spyder's editor is very heavy in Mavericks
I've been writing Python code in Spyder for some time, but when I moved from Ubuntu 13.04 to Mavericks, the editor was too heavy and I got stressed when moving the cursor.
After various searches, it seems that Mavericks' App Nap is having an adverse effect. spyderlib issue1623
Solution
The solution seems to be different depending on how you installed Spyder.
When the package is installed
Disable AppNap.
Disable from "Get Info"
Disable from terminal
cd /Application/Utilities
defaults write org.spyder-ide NSAppSleepDisabled -bool YES
When installing from source code
First, get a module called appnope
pip install appnope
Then edit spyderlib / start_app.py and add the following line to the beginning of the import statement:
import appnope
My Spyder is now lighter. If anyone is heavy and in trouble, it might be worth a try.
