Freezing at Several Points

I've been having issues with both the client and game going unresponsive for periods of time averaging about 15 seconds. They consistently happen when the client opens, when I click "next", and at the login screen. It also happens seemingly randomly both in-game and in character creation/server selection. Any help would be appreciated.
