CodeIgniter – Benchmarking

Setting Benchmark Points

If you want to measure the time taken to execute a set of lines or memory usage, you can calculate it by using Benchmarking points in CodeIgniter. There is a separate “Benchmarking” class for this purpose in CodeIgniter.

This class is loaded automatically; you do not have to load it. It can be used anywhere in your controller, view, and model classes. All you have to do is to mark a start point and end point and then execute the elapsed_time()function between these two marked points and you can get the time it took to execute that code as shown below.

   // Some code happens here  

   echo $this->benchmark->elapsed_time('code_start', 'code_end'); 

To display the memory usage, use the function memory_usage() as shown in the following code.

   echo $this->benchmark->memory_usage(); 


Create a controller called Profiler_controller.php and save it inapplication/controller/Profiler_controller.php

   class Profiler_controller extends CI_Controller {
      public function index() {
         //enable profiler
      public function disable() {
         //disable profiler 

Create a view file called test.php and save it at application/views/test.php

<!DOCTYPE html> 
<html lang = "en">
      <meta charset = "utf-8"> 
      <title>CodeIgniter View Example</title> 
      CodeIgniter View Example 

Change the routes.php file at application/config/routes.php to add route for the above controller and add the following line at the end of the file.

$route['profiler'] = "Profiler_controller"; 
$route['profiler/disable'] = "Profiler_controller/disable"

After that, you can type the following URL in the address bar of your browser to execute the example.

The above URL will enable the profiler and it will produce an output as shown in the following screenshot.


To disable the profiling, execute the following URL.
