Why does SystemUIServer cause high CPU usage? The SystemUIServer process is taking 30% of my CPU. Searching around reveals a Snow Leopard daylight savings bug which is solved by removing the clock from the menubar. I am on Lion and I have tried this without success. Any ideas on how to fix this?
Same problem here. The problem is caused by a third-party widget that uses the internet. For me, dropbox was the problem. If dropbox is updating my files, systemuiserver keeps using a high amount of CPU .. the only solution is to force quit it (using terminal or activity monitor) or disabling the third-party widget.
