Pay Per View plugin speeds over 15 seconds plus. How can this be fixed on Upfront/Fixer's theme

Hey folks,

***By the way, support access is enabled via wpmudev's dashboard.

See attached. the Pay Per View plugin is over 15 plus seconds and really slowing down the site page speeds. The site is on Upfront/Fixer's theme.

The big problem is with the Pay Per View plugin (which is the main plugin that will be driving this website). The next is the Upfront/Fixer theme itself (but not nearly as important compared to fixing the Pay Per View page speed issue).

Please let me know what can be done asap.
