Why KITE API response take long time in ajax but php code executed quickly?


I made a PHP application and it requires API Response from a server and it checks with mysql database.

Every time it takes long time to execute, minimum time to get response is 3 seconds and goes 90 seconds and so on.

I have attached the screenshot of two files for one is continuous request delayed response and another is waiting time.

I want to know the reason for the waiting time and blocked time in response. But when I check the php code execution it done in less than one seconds.

Whether I want to improve php code or that KITE API server?
