Question: i have a page made AJAX/HTTP Request and the result is JSON formatted .
using JQuery GET : 

```
$.get('..',{..},function(data){
   console.log('Hey Iam finish !');
},'JSON')

```

The problem is `console.log('Hey Iam finish !');` executed after many seconds (3>) as Firebug says . 

Server : WINDOWS IIS ( Unfortunately ) , PHP .

Server Code : 
i try to remove JSON and just echo :
`echo "HI";` 
the result is same . 

**UPDATE** 

Summary : Firebug says the AJAX request finish but result appear only after 3> seconds

Answer: 
Your serverside code is taking a long time to process, you should check to see if there is any time to gain in optimizing there. Your Javascript/jQuery is not the problem here.
The problem was in FireBug 1.8.4( FireFox 5/Linux Mint) it not give the accurate response time , i try firebug lite on chrome , and it give the accurate one .
