Looking for a benchmark tool

[Baender]

It may seem a strange request for a firewall solution. But is there a way to install a benchmark tool on the OPNSENSE? I have really spent a lot of time on my question. I just want to get a feeling for the maximum power consumption and waste heat of the CPU. To do this, I want to run a benchmark on the OPNSENSE temporary. My problem is that no solution works on the OS and are only designed for Ubuntu and Co.

# pkg install stress-ng

be prepared with a quiet time to run it. It can crash the machine. Not a defect, just system "too stressed"
