membership plugin is eating system resources

Hi there,

I wanted to let you know that it appears version of the membership plugin eats up system resources. Upon upgrading to this version yesterday, our website (which sees about 11,000 visits per day) page load time went from 5seconds to about 30seconds.

We would love to use the new version of the plugin since it offers a working version of pop-up registration, but this issue forced me to revert back to version

Is there any chance the developer of the plugin could look into this issue on his/her end?
