How to increase ksoftirqd usage for testing

Question

I have developed an application to calculate the percentage of ksoftirqd usage per CPU core and I want to test this. I am flagging an alarm if the usage is more than 50%.

To test this, I need to load the system in such a way that it increases the "ksoftirqd" usage drastically.

Are there scripts/tools available to do this?

I found a way to increase Ksoftirqs. I am doing syn flood (link) which is increasing the the load on ksoftirqs. Thank you

The program was written in python2 but can be converted to python3 easily.

Since (your) question was "Are there scripts/tools available to do this?" perhaps an example or two would be helpful here? – Jeff Schaller Jun 23 '21 at 17:19
