excuse me if you know this already..
(for XP/PC)
While logic's running, press ctrl alt del to bring up the task manager, go to process and right click on logic, choose priority and set it to a higher value....( Not real time!!, i have it on high. Real time makes nasty results be carefull!!!!!!) and everything will run smoothly and perfectly. Remember that you've got to do it everytime you start logic. I dont know how to set it permanently...
This made A LOT of difference for me now i can`t even provoke an asio overload message
