I am trying to edit a large MATLAB file (e.g. approximately 8000 lines of code) in the MATLAB Editor window. However, the editor is very slow to respond to keyboard input. There is a significant delay between a key press and the display of the character on the screen.
I have disabled the following features from the Preferences – M-lint (R2009b) or Code Analyzer (R2010a and after), Autosave, Code-folding and Syntax highlighting. Additionally, I have also tried increasing the Java heap space but I do not see a performance improvement.
