Question

I am using xampp version 1.7.7 on windows 7. I am trying to do that when you click save image it would send information to save_record.php in the background. I do this with

$.ajax({
      url: 'save_record.php',
      data: values.join("&"),
      success: function(data) {
            //document.write(data);
          }
    });

And it is clearly not the issue. The problem is that the response is very slow and I am unable to find the reason for it. Below I add the data I received from chrome speed tracer. Firebug is also showing all responses above 1 second. They come in format like 1055ms or 1035ms which makes me think it gets stuck somewhere for one second. If that was not weird enough, it starts making the requests fast (30-50ms) at some time and that is a perfectly usable application for me. Otherwise that 1 second delay is killing it. I once killed process explorer.exe and added as a new task and it worked. But the next time it didn’t. I restarted the pc – it is one second… And while I was typing this question it started doing those fast requests. Once it starts doing them fast it’s all good, but when I start xampp (or open my laptop from sleep) it is usually slow (1sec+). This is a somewhat self solving problem after some time (like 5-10mins usually), but it is annoying and both curious as why this is happening 🙂 Hopefully I was clear about the problem.

P.S. I tested and the difference in time from first php tag to last one is ~20 ms, so I assume it is not PHP cache that is acting up?

P.S.2. I would provide any other data needed, just not sure what to look at 🙂 Just name it.

UPDATE: added Chrome’s network tab.

UPDATE: after reinstallation of xampp the problem still persists:

Uncommenting the line 127.0.0.1 localhost in C:\Windows\System32\drivers\etc\hosts solved the problem. The speed just jumped up incredibly. I found this advice in here. Actually even the speed of Chrome opening other pages increased a lot o.O
