Windows performance recorder

What is it?

jPerf is a tool for determining how much load your computer is under over a period of time. Useful for seeing how many of your system resources are being used by a process or application, and where bottlenecks may be.

Currently, jPerf can monitor CPU load, GPU load and RAM usage.

jPerf also has the ability to place markers through a performance recording by clicking the Marker button. This can help you keep track of what is going on during your recording.

How do I use it?

  1. Click "Start Recording"
  2. If you want to add a marker, click "Edit -> Add Marker"
  3. When finished, click "Stop Recording"
  4. The "View" menu provides different viewing options, including the ability to hide markers and smooth out captured data.

If you have recorded two jPerf captures and wish to merge them together:

  1. "Import -> Merge jPerf Capture File"
  2. Select a jPerf Capture File
  3. Enter the time (in seconds) to place merge the capture file
