How To Improve WooCommerce Performance

Having a large WooCommerce store can seriously slow down the performance of your website and even affect the buyer’s decision or ability to buy. Here are some quick fixes you can implement on your WordPress site to dramatically improve WooCommerce performance.

1 – Optimise Images

woocommerce performanceWhen your store has more than 10 products each with their own unique image, it will likely take longer for web browsers to download your site upon a user’s visit. Good image optimiser like WP Smush will compress images without losing any of their quality and bring the size of your overall site down.

This is one of the easiest ways to speed up your WooCommerce store. All you need to do is download the plugin, install and use the Bulk Smush function to compress and optimise all your images.

2 – Deactivate Unnecessary Plugins

In order to find out which plugins are slowing down your site, you can use a nifty little plugin known as P3. It will analyse your site and tell you which plugins are slowest. Alternatively, you can deactivate each plugin and activate them one-by-one to see which one is slowing down your site.

3 – Increase WP Memory Limit

You can check your WP Memory Limit by going to the WordPress admin > WooCommerce > System Status and look at the value for WP Memory Limit. The default is normally set to 64 MB but you can increase this to 96 or even 128 MB depending on your needs. You can do this editing your wp-config file. Scroll down to line 83 or around that area and look underneath the line that states

define('WP_DEBUG', false);

You should add the following lines under that if they are not already there:

define( 'WP_MEMORY_LIMIT', '128M' );
define( 'WP_MAX_MEMORY_LIMIT', '256M' );

You should always check with your hosting provider before raising your memory limits and always back up before making changes to configuration files. If you are unsure about how to change the limit, your hosting provider will be able to show you how to do this.

4 – Remove Bad WooCommerce Extensions

There are some great extensions for WooCommerce like adding new tabs, improving the lighbox features and more. Sometimes, these can however conflict with WooCommerce code and you should identify which ones are slowing you down and deactivate them.


As you can see, you can use some quick fixes to speed up your WooCommerce store without spending too much time.  By simply optimising images, identifying troublesome plugins and increasing your WP Memory Limit, you will be getting more sales from a faster WooCommerce site.
