Performance issue on Ionic using the side menu


Hi all:

I started to build out an sidemenu project. And, the more I
build the slower the app gets.

Now, I have all the controller in a single file, Is that an issue?
I like the coding style. I only a few changes to the css.

Some of is due to complex UI elements- which is fine.
I am also using alot of localstorage is that also an issue.

Would getting all the *.get from localstorage on startup
help? And, how would I do this?
