How to check what loads a page on a local server?

Question

Laravel

I'm using octobercms and developing an application site on a local openserver server. part of the data is loaded from the local database, and part from external api. Using the user plugin, in the onRun function - added requests via guzzle, maximum 3 requests. I understand that the OnRun function Works on any page where the plugin is connected, and these pages take a terribly long time to load, in the browser most of the time the connection is lit. If you directly connect to api in the form http://ip/request , then it works instantly. How to find out what is the reason?
