Recommendations for running hyperscan on multicore setup

Hello,

This is not directly a issue on the hyperscan package. Posted it here if incase folks have some suggestions.

I'm currently experimenting with using Hyperscan for regex matching in a test service written in Go. To interact with the Hyperscan library, I'm using the [flier/gohs](https://github.com/flier/gohs) package.

So far, I've had a great experience using Hyperscan on a single-core machine. However, when I tried running it on a multi-core machine, I didn't observe any significant performance improvements. You can find more details about this issue in this link: https://github.com/flier/gohs/issues/56.

The tests in the link are benchmark tests written in Go. I do see from the blog that the performance increases linearly with the cores. https://www.intel.com/content/www/us/en/developer/articles/technical/introduction-to-hyperscan.html).

I am unable to understand why the perf doesn't increases linearly. I'm not sure if I'm missing any configuration or if I'm testing it correctly.

Do you have any suggestions?

Thank you!
