setInterval() method in my application ...

[arunjp]

Hi !
I've used setInterval('doScroll()', 50) method in my application. I just want to make sure that the function doScroll() will be executed for every 50 millisecond, will there be any performance issue like 100% CPU usage in the client machine. What could be the optimal time interval for setInterval method so that the application would not give any CPU usage problem even for low config machines.

Thanks
AJP

setInterval(sString|fFunction,iMilliseconds):

will force sString or fFunction to execute every iMilliseconds, but only when the interpreter has a chance. In other words, setInterval will rarely (if ever?) take over the cpu. If you ware doing some absurd dhtml changes and executing every 1 millisecond, you may notice a performace issue (probably a lag). jared@eae.net -
