Do you use any task killers, clean masters, antivirs etc??
I am on stuck 4.4.2Never had a problem on my Note 3. Have had this problem many times on my original Note and Galaxy S however.
You could try PurePerformancexX or try a completely fresh stock ROM flashed using ODIN and your choice of ROM from Sam Mobile.
Or simply use a different custom ROM flashed from your custom recovery. Making sure to do a complete wipe before hand (or during installation with Aroma Installer).
What ROM are you using?
This is a very hard solutionWell I'm currently using MultiX with stock kernel, virtually nothing selected except for things like Dropbox and other necessities that I use. It's as light as you want it to be. Give it a shot.
Also if it's games that are lagging you can try using custom Kernels.
One that springs to mind is Aurora which has a GPU overclock.
All controllable using Synapse which installs at the same time Aurora is.
Good luck
with wipe data all user data will be deleted but phone to become fastest than ago.
