Ubercart is running slow because it is currently sharing it's physical server with several other high traffic sites including one running a "web chat" with maybe 100 people. As soon as the chat is over (about 1 hour) Ubercart should be back to normal. Some time this weekend we are moving the other website to it's own server which should fix this problem.

Some old posts, and all old juice got lost in a crash about three weeks ago.
Peace, Andy
