High CPU Utilization

Nate Smith May 23, 2019 04:17PM UTC

I am seeing an extremely high usage on my CPU in burpsuite. I am also seeing the RAM consumption go up to 16-17GB in a session. I am in the middle of a test of an API for a client. I can kill burp and then reload it. Then it is okay for about 15-20 minutes before returning to high usage. Let me know what you need to determine what might be causing this issue.

I forgot to mention that I am using version 2.0.21beta

I have noticed that if I disable the the default live passive crawl and live audit, then I am not seeing the same issues with high CPU and RAM usage.

I updated to the latest version and still seeing the same issue, even when using intruder.

Nate, do you have performance feedback enabled (User options > Misc > Performance feedback)? If so, could you provide us with your diagnostics (Help > Diagnostics)?

Nate Smith May 30, 2019 03:02PM UTC
Yes, I do have it enabled and will send an email with the diagnostics.

Thanks Nate. We’ll investigate and let you know when we’ve made some progress.

Nate, could you check whether you are still experiencing issues with the latest version of Burp (2.0.25beta)?

It would also be really useful for us if you could disable all your Extensions when you’re trying this.
