Magento Profiling and Database performance

Magento Profiler is a built-in internal Magento debugging tool, which is used for debugging. It plays a vital role in Magento development. We have various tools for debugging, such as - New Relic, Xdebug, etc. Using these tools, we can get useful information and check our website with their colorful graphical outputs. But these debuggers do not have much idea about the structure of your Magento application. Therefore, Magento has an internal debugger named as Profiler.

Profiler allows us to collect different information about controller, blocks, actions, events, templates, observers, etc. on various application execution stages. It also allows us to get a report of how long each part of a Magento store is being loaded. Magento Profiler reports the time taken by the block of code to execute, number of times the block of code was executed, and the memory used by it while rendering a Magento webpage. It specifies a block of code, which makes the loading of the page slow.

Why needs Magento Profiler?

Gradually, every system performance slows down after it is loaded with more content and extensions, and many logs are generated for it. You need to enable the profiler to know what is slowing down your Magento 2 performance. Magento Profiler identifies the performance problems on the server-side.

There are three types of profiler supported by Magento:

  1. HTML - added to every footer of all the pages on the frontend.
  2. CSV file - exported in magento/var/log folder.
  3. Firebug

How to enable Magento Profiler?

To enable the Magento Profiler and perform debugging, follow the below steps -

Step 1: Add this line of code in .htaccess file present in Magento root directory magento/pub/.htaccess.


e.g. SetEnv MAGE_PROFILER html

Precisely, the <type> 'html' is for HTML output, 'csvfile' is for CSV output or 'firebug' for Firebug output.

Step 2: Enable the developer mode using command:

Or you can go for .htaccess file and un-comment the developer command by removing hashtag (#).

Step 3: At last, compile and refresh the cache.

Magento Database Performance

It is a very time-consuming process of Magento store - its interaction with the database. Optimizing Magento Database is an essential task to maintain the Magento site. Maintaining and cleaning the old Magento Cache and Log records can improve your Magento database performance.

Magento saves a lot of databases because of tracking. The e-commerce system must have a tracking module. It shows the information when something goes wrong with their order. Below are some points to improve the database performance -

  • Optimized database queries.
  • Unused data must have to be clean up regularly for better and fast performance.
  • Configure settings and limits of the database server (for example - memory setting, sort buffer optimization, and query cache, etc.
