How to make flexible a module

I recently install a module for the rest of my project. This add-on was running my wish, but the problem is that it has made my application slow, too slow.
I want a light and fast application.
possible? Help me

Which “module” (plugin?) did you install?
What exactly is slow now?

Ok thanks
It’s a calendar module (ionic2-calendar)

I’d suggest using Toast controller for date checks.

Explain yourself clearly…
