100% CPU utilization in Burp Suite Pro 2.1.03

Sameer Mohite Sep 26, 2019 06:57PM UTC

Burp Suite Pro 2.1.03 keeps causing 100% CPU utilization when running an audit scan (earlier known as scanner). The scan task works for approximitely 2500-3000 requests after which it stops. Stopping the scanner does not cause the CPU utilization to return to normal levels. I have checked this with
- all extensions disabled
- all other tasks paused

Could you try updating to the latest version of Burp (2.1.04)?

Are you using the platform installer version of Burp Suite?

Is the application you are testing public facing?

I have found the same high CPU issue with 2.1.04 and the scanner, when starting it via the command line through java jar etc etc.

If you install burp via the Windows installer, rather than via the jar file, it seems to manage it's resources at bit better - it's still high CPU resource intensive though, but it's a bit better.
