Why Magento 2 Profiler
In Magento 2, we offer a powerful built-in profiler that allows you to analyze and optimize the performance of your website. By using the profiler, you can gain valuable insights into the execution time of specific code blocks, helping you identify and address any performance bottlenecks.
There are three approaches to enabling or disabling the Magento 2 profiler:
- Using the .htaccess file
- Using the Command Line Interface (CLI).
- Creating a manual file (profiler.flag).
1. Using the .htaccess file
- You can easily enable the profiler by adding a line of code to the .htaccess file located in your Magento root directory. Once added, simply refresh the web page to see the profiler in action.
- If you wish to disable the profiler, you can either remove or comment out the aforementioned line in the .htaccess file.
- To enable the profiler, add the following line to your .htaccess file
SetEnv MAGE_PROFILER html
2. Using the Command Line Interface (CLI)
- Magento 2 provides CLI commands that allow you to enable or disable the profiler.
- To enable the profiler, use the following CLI command:
php bin/magento dev:profiler:enable <type>
- Replace <type> with either csvfile, firebug, or html. By default, the profiler output is set to html if no argument is passed.
- To disable the profiler, simply execute the following CLI command
php bin/magento dev:profiler:disable
3. Creating a manual file (profiler.flag)
Enablement: Magento 2 offer the ability to manually enable the profiler by creating a new file within the designated project directory, specifically in the “var/profiler.flag” location. To enable the profiler, it is imperative to include the desired output type, such as “html,” within the profiler.flag file.
Disabling: Should you wish to deactivate the profiler, a simple course of action involves removing or renaming the “profiler.flag” file.
-> file path: project/var/profiler.flag
-> open profiler.flag
-> Add html only for the output
-> close the file
-> Check in the web browser
Add Our Custom Profiler:
With the help of our custom profiler, you can trace specific blocks of code in your Magento application, enabling you to identify and overcome any obstacles that may impact performance. To utilize the custom profiler, you can leverage the start() and stop() methods provided by the \Magento\Framework\Profiler class.
To trace a block of code, you can start the profiler by using start(“custom-profiler-name”) at the beginning of the code block, and then stop it with stop(“custom-profiler-name”) at the end of the code block.
\Magento\Framework\Profiler::start('custom-profiler-name');
/***
* Here you can add your code so the custom profiler will calculate the execution time or measure the performance of code
**/
\Magento\Framework\Profiler::stop('custom-profiler-name');
By reviewing and enabling the custom profiler, you can harness the full power of Magento 2’s profiling capabilities to optimize your website’s performance and enhance the overall customer experience

Profiler html Output :
Below is the html output and you can see the multiple columns like TImer Id, Time, Avg, Cnt, Emalloc, and RealMem, let’s describe them in short.
- Timer Id: Provides the name of the executed code block.
- Time: Indicates the duration of execution in seconds.
- Avg: Represents the average execution time in seconds.
- Cnt: Abbreviation for Count, indicating the number of times the specific code block was executed.
- Emalloc: Refers to the amount of memory allocated by PHP for the individual operation, measured in bytes.
- RealMem: Represents the actual memory consumption during the operation
