A simple but effective Mac speed-up tip
Authored by: albertoricart on Nov 28, '05 09:57:15AM

Sure, if you have more icons, you have more windows, and you consume more memory. If this really has an impact on the performance of your machine, you really need to buy more memory or get a faster CPU.

The WindowServer in most cases is memory bound. That is it trades computation time for memory because most of the time it is faster.
For this reason, most applications use buffered windows (there are other options, non-retained, and retained). That is, for each window, there will be another window that is off screen. The reason for this is that when the window the user is interacting with needs updating (ie, you move the mouse over the window) the WindowServer simply needs to copy the damaged region from the offscreen window and blast it over to the visible one. Similarly when the content of your window changes, applications are only supposed to update the region that changed. This drawing is performed on the buffer, which then is copied over to the 'visible' window.

Desktop icons are both a nightmare and a convenience. Old NeXT machines didn't allow you to put things in the 'desktop'. Which was great because it forced you to file your stuff in the right place from the get go.

<http://www.smartsoft.com/products/dotfiles/dotfiles.html> provides a service that allows you to toggle the use of the desktop (you still can put your stuff there, you just don't see it).

And this is exactly the problem with the PowerBooks. I have a 1.67Ghz G4, I can't buy a faster CPU. I have 2GB RAM, I can't buy more RAM. All I can do to get acceptable performance while using the Desktop is to upgrade to a G5, which is not extremely portable, despite the handles. :-)
