Request ajax takes a long time to execute

Question

I have an ajax request in which the method used is the POST, the information I pass is with a formData object, in it has some photos that can vary from 1 until 15, when I run it in localhost does not last 1 second, now that I’ve uploaded the site to the hosting server it takes 120 and stops running, my question is, what might be causing this since the local server runs almost instantaneously?

$.ajax({
    url: '../controller/inserir_prova_banco.php',
    method: 'POST',
    data: formData,
    processData: false,
    contentType: false,
    success: function(data){}
});

Friend, there are several factors that can cause this.

First, the local server latency is zero. It will run instantly.

Now when it’s web server, somewhere else.... Oh yeah, look what might be trouble to get so slow.

1- Your internet is extremely slow and slow 2- There may be a route problem, from your computer to the server 3- Your web server, may be over loading with many Simultaneos clients.... 4- Its application is poorly structured etc....

There are several factors... but what I believe is, is that your server is slow.... if you do not have POST files... I think it is your server even
