You use 4 worker threads and 4 chrome workers. Therefore you have 16 Chrome instances running... Sometimes it's even doubled because Chrome uses another supervisor process...

If you don't won't to reuse existing chrome instances, you should use configuration chrome.strategy=dedicated-process.

Ok, what is the recomendation?

I see chrome-pool as a good strategy.

Here i See exactly 80 chrome process running.

Try it with the default

"chrome": {
"numberOfWorkers": 1,
"strategy": "chrome-pool",
}

For me on Windows, chrome creates 5 processes per worker then.
If it bothers you, go with dedicated-process strategy.
