Is there a way to optimize the membership plugin for faster performance?

My site is running very slow and I need to optimize it.

I am willing to migrate to a new server, but I wanted to analyze my site first. (Currently I'm on a Godaddy Shared hosting account)

I used the P3 Plugin Profiler and found that the membership plugin is 43% of my load time.

Any suggestions for the best way to move forward?
