Notepad++ slow typing and high CPU usage
This can be caused by the function completion scanner if its character limit is set to more than 1.
Typing is slow. If you hold down a letter key, the characters don’t appear until you release the key. During key-hold, N++ will appear to be using a high portion of CPU.
- In Notepad++, open Settings menu, Preferences…
- Go to Auto-Completion
- Where it says ‘From 3th character’ (or whatever), click the number, change it to 1
- You can close the box and test the changes right away, it should be responsive again.
If you don’t use function completion or parameter completion that much, then turn them off in that settings dialog for a greater performance boost.
