CoursePress Performance Problem

Hi, I have a new CoursePress installation with only 16 students so far. However, the app has become extremely slow when users are logged in. Many times pages become take over 60 seconds and time out for logged in users. I profiled these pages with NewRelic and found what is in the attached screenshot.

One thought is that maybe these are background tasks that should be completed on the backend, but are not completing because the script times out first?

This is on, which is on a Rackspace VPS server with nothing else running on it. In addition MySQL has been tuned for performance. Feel free to sign up, begin working on a course, and going back to the Dashboard to experience the slowness.

Anyone have any ideas? Thank you for your help!
