Optimisation issues and stutters

This will probably involve more advanced coding to what I'm used to, but is there any way of reducing stutter and improving optimisation? I have a simple 2.5D platformer prototype in the works. The fact things are working correctly are the main concern, but I've noticed there's quite a bit of stutter going on whilst playing, especially when I touch a trigger in my scene. Even things like my parallax effect seems to be stuttering.

 

Have you tried using the profiler?

The profiler.

You can probably also google to find some tutorials on good use. In essence, it shows you which parts of your code are taking a lot of time.

 

Okay, I'll look into it. Thanks.
