Big Meter Pro is a free CPU meter for your desktop, along with two dials for the memory and disk (partition) usage, and an alarm clock. This is a simple and nice utility, having many features and high resolution graphics, allowing you to monitor and easily read a few of the important computer parameters. Version 2 offers you the possibility to enable or not the 'smooth motion', useful for slow computers. The entire code of this new version is optimized, so that BIG METER PRO itself loads the processor with only 1 percent on a PIII / 700 MHz, having the CPU percentage and smooth motion options disabled. Also you can enable alerts and set an alert percentage for all the parameters displayed by this utility (between 1 and 100%), and an alarm for the analogue clock. A small window will show up when an alert occurs, but a single mouse click is enough to make it go away.
