Poor server performance on capable machine

Hello @clientsfsc

I will recommend to examine if any of the WordPress plugins are causing the extra resource usage on the droplet. Sometimes a faulty plugin can consume a lot of memory or cause CPU usage spikes.

You can monitor the droplet resource usage using top and other tools. We have a tutorial that covers this process here:

Hi there,

It looks like that you are running quite close to the memory and CPU limits. It might be worth adding some extra resources like RAM and CPU to that Droplet.

Other suggestions would also include:

• Add a swap file to have some extra memory buffer:

• Add a caching plugin like WP super cache or WP rocket. That way you will reduce the overall load on the server itself
• Use a CDN like Cloudflare
• Check what processes exactly are using most of the memory and CPU and possibly try to tweak those services for better performance
• Use Wordfence to quickly do a scan of your website to verify that there is no malware that could be causing the problem. You can remove the Wordfence plugin after the scan as it tends to slow the website.

Let me know how it goes!

Best,

Bobby
