Find and log expensive requests

Hi,

I have a Woocommerce store that usually works well, but sometimes there are very expensive script executions. I want to find out which requests result in these expensive script executions and log them so I can analyze them. However, I have no idea where and when these expensive script executions occur. Can I find out with the plugin? Or do you have a different plugin (free or paid) which can do this?

Thank you and best regards,
Helmut
