Question

Woocommerce takes CPU Usage to 107%

Hi there!

I just deployed a new 5$ droplet (1 GB Memory / 25 GB Disk) with Wordpress preinstalled (WordPress 5.5.1 on Ubuntu 20.04).

My idea was to run Woocommerce to sell some courses.

Since there won’t be hardly any traffic for now, I started with the smallest droplet.

After installing Woocommerce, I noticed that I couldn’t access any page of the website anymore.

Checking my droplet graphs, I saw that the CPU usage grew to more than 100% and I had to shut it down and turn it on again to be able to access my website.

If I try to add a new product to Woocommerce, the same problem happens again.

There are just Woocommerce and thrive themes installed in the droplet.

Do you think that this droplet is not strong enough or maybe I’m doing something wrong?

What do you recommend?

Thanks!

Hi @Matthevv,

Usually, I would suggest optimizing your Droplet but even optimizing it wouldn’t save the current situation.

Yes, I think the Droplet is not strong enough to handle your Theme and the Woocommerce plugin. More often than not, this plugin is the cause of all issues with a WordPress website regarding slowness and other stuff.

Having said that, I’ll recommend you to configure SWAP on your Droplet to prevent it from hanging up like that:

Once you have that, you can also optimize your Droplet and your Website.

On the Droplet side, I’ll recommend using Opcache + php_fpm. These two will tremendously help you with how your Server is handling your Website.

Regarding your Website, I think you should install a Caching plugin, a plugin to optimize your images and similar stuff.

One way to guard against out-of-memory errors in applications is to add some swap space to your server. In this guide, we will cover how to add a swap file to an Ubuntu 20.04 server.
