10.4: Cut down on the World Clock widget's CPU usage
Authored by: msalsbury on Sep 19, '05 11:53:05PM
Actually, the performance situation with the World Clock Widget is a LOT worse than people suspect. I recently began testing the Widget's performance on 10.4.2 by leaving the Dashboard open as much as I can on a spare Mac and taking snapshots of process activity every hour. What I've found is that the other default Widgets (Address Book, Calendar, Weather, and Calculator) take little to no CPU or RAM unless they're actually doing something - and even then they take very little. World Clock, on the other hand, grows steadily as it remains active. After leaving a system up for a week or two, I was shocked to find that World Clock was consuming over 46% of the CPU and over 150MB of RAM. I'm currently monitoring it over a longer period of time to get a better picture of the problem. If you're curious as to the current status, it can be found on my web site at:

10.4: Cut down on the World Clock widget's CPU usage
Authored by: heyotwell on Oct 03, '05 04:23:56PM

After reading this, I started monitoring my four running World Clocks, which are unmodified 10.4.2 versions. No matter how long they're left running, they never consume CPU time when the Dashboard's closed, though they do consume some memory. I don't reboot unless required by software updates, which is rare. In other words, I don't see the symptoms you describe at all.
