Simple Codeigniter Site hanging (8min+) - where to profile/benchmark?

My CI site will sometimes just hang - server seems to take forever to answer my request, i.e. when just loading the homepage, and other pages too. It's quite random and only does it sometimes.

I turned on profiling and hit the homepage, this was the result:

enter image description here

Here's the home/index method

function index()
{ 
$this->output->enable_profiler(TRUE);  

$this->benchmark->mark('template_sets_start');
   $this->template->title('Yay, welcome to my site');  
   $this->template->js('home.js,cycle.js');             
$this->benchmark->mark('template_set_end');

$this->benchmark->mark('template_load_start');
   $this->template->load('template/home'); 
$this->benchmark->mark('template_load_end');
}  
}

Since the time returned for the template stuff is low, I can assume the lag isn't happening anywhere in the views.

An ideas or suggestions?


===EDIT===

One thing I found is the config is setting the base_url dynamically. Code below, could this potentially cause slow-dows?

$config['base_url'] = ((isset($_SERVER['HTTPS']) && $_SERVER['HTTPS'] == "on") ? "https" : "http");
$config['base_url'] .= "://".$_SERVER['HTTP_HOST'];
$config['base_url'] .= str_replace(basename($_SERVER['SCRIPT_NAME']),"",$_SERVER['SCRIPT_NAME']);
Solution

  • Execution time for "Template Sets" is 0.0000, because you missed "s" in mark's name.

    Change:

    $this->benchmark->mark('template_set_end');

    to

    $this->benchmark->mark('template_sets_end');
