- Fire up Activity Monitor looking for problems
- Remote desktop into the server to look at CPU use

This free SP is pretty much a monster SP. How monster? Here's it at 10% zoom
Yeah, monster. How much? Free! (Friendly Reg-ware). Will have to share this at work tomorrow (Because I know not many of you there subscribe to my feed, no matter how often I whine about that... hum... I wonder if my whining is turning them off from subscribing? NA! Never! They love my whines! I'm sure it doesn't bug anyone!... um... right... :/ )
