Magento 2 Slow? Steps to Speed Up Magento 2

I used Magento 1.9 and it was okay. It wasn’t as fast as a simple WordPress site yet I had many customers with no problem but why is Magento 2 so slow?

A visitor on my website recently shared his experience with me on how he felt Magento 2 is slow. He was quite frustrated as he could not work with the admin panel most of the time. Each time he tried to save a transaction he would end up with a spinning wheel or an error. I was able to resolve the issues on his online store after debugging for a couple of days and with few optimization tweaks. This experience leads me to write this blog – why is Magento 2 so slow?

Honestly, it is not slow by itself. This may be due to some CSS or JavaScript conflicts or could be a third party extension installed on your website that is chewing up a lot of resources. It could be also that the extension codes are conflicting with some core files. All it needs is patience and an expert magneto developer to find out what is causing this slowdown.

Why is Magento 2 so slow?

  • Slow hardware: Did you know that your magneto store needs some basic technical specifications that help run your store seamlessly? Most of these are related to your server and hosting space. Your server needs to have a Linux based operating system with up to 2 GB of RAM. Additional memory is required for large transnational based stores having a heavy database. Cloud-based hosting has helped many eCommerce stores to address this issue of scalability. You need Apache 2.2 or 2.4 with mod_rewrite and mod_version modules enabled. This is mandatory. Alternatively, you can choose nginx 1.x as well. You can check on prerequisites to know more about these configurations.
  • Third-party extensions: There are tons of Magento extensions available in the community which is available as the paid or free version. Community coders and programmers who write these extensions differ in skill-sets. This may result in poorly coded extensions. Using even on such extension would result in a slowdown of your system. Consider making a list of all these extensions and check through reviews and comments. Upgrade the extensions to its latest versions as most developers would release fixes based on reviews received.
  • Disabled Full page cache: Caching helps load web pages faster by reducing the request time to the server. It pre stores files of your web pages and quickly loading them on client request. Enabling caching will definitely help you improve your site performance.

There are several other reasons that can cause your store to slow down and this can only be fixed after proper debugging of the codes. Let us now find some tweaks to do in Magento 2 Admin panel that will help fix the slowdown issue.

  • Merge or Minify CSS and JavaScript Files: Magento 2 slowdown could be because of the store theme. One of the main reasons for a slow Magento store is the theme that is coded needs cleaning. Unformatted codes, unattended loops would result in too much of process time.
