Lag typing large file with Matlab extention

[pjacquet88]

Issue Type: Performance Issue

On large matlab files >800 lines,
I have several seconds of lag when typing a letter or even when I hit the arrow to move inside the code. Suprisingly backspace or ctrl+z works intantly. I do not have this latency when disable matlab extention but also my emacs extension. Could it be a compatibility issue ?
