Each Hostinger hosting plan comes with a set amount of resources. The resources determine how well a hosting plan handles the load.
While checking the usage of your hosting plan resources, you may notice the message “Your websites could experience slower performance”:
Let's 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 gets slower and starts scheduling requests from your visitors instead of serving them instantly. There will be no error messages, but the website will feel sluggish.
Find out what are 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 on your website.
Usually, high CPU usage is caused by poorly optimized website code. We suggest you:
If you tried the above suggestions, but the site's performance is still poor, it indicates that your website has grown and needs more resources to keep up with the load. In this case, consider upgrading your hosting plan.
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 above-mentioned solutions apply.
RAM and Processes
When your hosting plan reaches the limit of processes or RAM, your website visitors may encounter the 503 Service Unavailable error.
It is critical to ensure you never reach these limits. If you reach the limit of processes or RAM 10-20 times within one month, it is a very strong indication that your website needs a larger pool of resources to handle the load. We recommend you reduce the number of processes to the minimum and, if the issues persist, upgrade your hosting plan as soon as possible to ensure the best uptime for your website.
