My moodle site is currently experiencing slowdown, particularly during login. It sometimes takes beyond one minute to login. A short login time is normally around 30 seconds. I am currently using bluehost. I have upgraded my account and should have plenty of resources available to run this site. It does run smoothly once past the login. I am running Moodle 2.3.1
I am not a programmer and have no idea where to start looking for a problem.
