How can I improve the responsiveness of an applications user interface. Initially my application caused the mouse to freeze or move in a jerky fashion. I then changed my program to do the heavy work in another thread (lots of pain).

The mouse now moves smoothly and never freezes, however if the user clicks on an interface element such as a check box it can take many seconds for the check box to change status. On a 500mhz iBook, "top" reports the the system is ~35% busy, which does not seem like much to me.

As yet I have not found any documentation that could help me with this problem any pointers or suggestions would be appreciated.


You need to understand what your machine is doing when it lags.
It it swapping? Is CPU usage high or low? Is it blocked somewhere?

Run top, CPU Monitor and/or iPulse, and get to know your machine
better.
