Addressing the “Your websites could experience slower performance” message on hPanel
Updated over a week ago

Each hosting plan here at Hostinger has a set amount of resources provided for it. The resources determine how well a hosting plan performs under load. You might have noticed the “Your websites could experience slower performance” message while checking the resource usage:

This article will go through the most important resources and how reaching their limit affects your website:


When you reach the maximum threshold for available CPU, your website will start working slower and scheduling requests from your visitors instead of serving them instantly. There will be no error messages generated, but the website will feel sluggish.

Consider and review your website's peak hours, and make sure your CPU stays below 80% during the busiest times. This will guarantee that all visitors have the best possible experience. Usually, high CPU usage is caused by the poorly optimized code of the website. This can be addressed by:

  • Revising your code

  • Reducing the number of plugins

  • Minimizing the number of cron jobs

  • Enabling caching on your website – for WordPress websites, we recommend the LiteSpeed Cache plugin

If you are still encountering poor performance after addressing these issues, it indicates that your website has grown and needs more resources to keep up with all concurrent visitors. In this case, you can benefit from upgrading your hosting 😊

Input/Output (I/O)

Disk I/O or disk throughput is a limit on how fast data can be written/read. This limit helps measure disk performance. When you reach the maximum threshold for available I/O, your website will slow down, similar to when the CPU threshold is reached. For this reason, the same solutions as for high CPU mentioned above apply.

RAM and Processes

When you reach the concurrent process, memory or RAM limit, your website visitors might get an error page such as a 503 Resource limit reached message.

It is critical to ensure you never reach these limits. Even if you reach the processes or RAM limit 10-20 times during the course of a month, it is a very strong indication that your website needs a larger pool of resources to handle all concurrent visitors. We recommend reducing the number of processes to the minimum and, if the issues persist, upgrading your hosting plan as soon as possible to ensure the best uptime for your website.
