Causes of Website Overload & How to Overcome It

For hosting users, there are often cases of website overload, causing website performance to be slow or even inaccessible. Overload here has many causes, it is necessary to check whether it comes from CPU, RAM, MySQL, hardware or software problems.

Servers are just like normal computers, sometimes running slowly when there are many processes running. To avoid overloads like this, you can upgrade the hardware and system. Similar to hosting when overload occurs, the best solution is to upgrade the package above it or you can upgrade to a VPS service.

Apart from upgrading, there is a cheaper and more interesting option to try, which is to find the cause of website overload. If you've found it, all you have to do is find a way to resolve the overload.

Causes of website overload.

So here we have divided the causes of website overload based on its category:

Overload CPU Usage.

Some causes of CPU Usage overload:

  • Traffic from websites/blogs that are too high.

  • Installing too many WordPress plugins.

  • Install scripts that consume CPU usage.

  • There is a bug/error on the website.

  • Endless looping.

  • Hacked hosting account.

  • Streaming media files on hosting.

  • A large number of script errors occurred on the website.

  • Using excessive cronjobs.

Overload RAM/Memory Usage

Some causes of RAM/memory usage overload:

  • There is a problematic script that is processed in server memory for a long time.

  • Most plugins that run require server memory.

  • Script/php is always active, putting a load on the server's memory.

  • Using excessive cronjobs.

  • Entry proses yang banyak dan bersamaan pada akun hosting.

  • Malware on always-on hosting.

  • High traffic of website visitors.

Overload MySQL Usage

Some causes of MySQL usage overload:

  • Using redundant database queries

  • Pulling data from database systems that are too large.

  • Not using a caching plugin to lighten the load when a database query comes in.

  • Using a "persistent" database connection puts a strain on server performance.

  • Use statistic plugins or scripts to collect data, counters, website visitors and more.

  • The website visitor traffic is too high resulting in a lot of database requests.

  • Database spam occurred, making the database full.

How to deal with website overload

The three problems such as CPU, Memory and MySQL on the overloaded website above can still be overcome, so take it easy. So here, please check how to solve website overload below:

1. View the hosting panel dashboard

cPanel monitoring

If you are using cPanel, you can monitor CPU Usage, Memory Usage and MySQL Usage on the cPanel sidebar. If the color is still green, it indicates that the space is still safe, if it is blue you need to be vigilant and if it is red, it indicates that it is overloaded.

2. Compress files when uploading to the server

So that disk usage does not fill up quickly, before uploading files you can compress them first, the goal is to make the file size smaller and lighter.

3. Use plugins from reputable developers

To be safe, try to use plugins and software from reputable developers who have created many plugins. Another risk that is often encountered is the presence of bugs, making it prone to being hacked.

4. Use cache plugin

The WordPress cache plugin will help website performance, especially in storing pages when they are first accessed. When a user requests a page for the first time, the cache plugin will save it so that when a second page request occurs, there is no need to retrieve files from the database, it can be directly from the stored cache. Recommended WordPress cache plugins such as WP Rocket, WP Super Cache, W3 Total Cache, WP Fastest Cache and so on.

5. Check Script

Check the script in your hosting files, make sure there are no errors that cause overload on the server.

6. Use Cloudflare


Cloudflare has a function as a CDN (Content Delivery Network) which functions as caching, so that when a CDN request occurs, it will provide the file requested closest to the user. So the server load can be smaller and does not cause overload..

7. Upgrade hosting services

Last but not least, upgrade your hosting service. If you are currently using a shared hosting service, consider upgrading to a Virtual Private Server.

Thus the discussion about the causes of website overload and how to overcome it. Please practice hopefully your hosting server will become normal again so that the website can be accessed normally.
