Perfy for Windows
Perfy for Windows is a small performance monitoring utility. Perfy uses the built in Windows performance counters to display information about CPU usage, disk usage, memory usage and network throughput.
The first time you start Perfy, you will be prompted to open the Options dialog and configure Perfy. Once perfy is configured and started, you will see an icon in the so-called system tray or taskbar notification area. A window will appear on the desktop that displays the performance counters you enabled in the Options dialog.
