Unfortunately, those plugins can speed up to some extent. To be in the competition and to make websites faster, we need to do some sort of optimization at the server level.

WordPress optimization with some server-level best practices can return a good yield out of a WordPress blog. So in this article, we will talk about those 10 server-level WordPress Optimization tips on how to speed up WordPress performance

But if you are on VPS or a dedicated server, then you can try these tricks to get the best out of your WordPress blog.

How To Speed Up WordPress Performance?

Here are some of the tips that you can follow to speed up your WordPress blog.

1. Use a Good Web Server

Many of us don’t look for a good web server while buying hosting. Apache is the default choice of almost all shared hosting and VPS. Unfortunately, Apache is not the perfect web server to speed up websites.

Instead, we can go for the Light Speed server which is offered by many hosts in their shared hosting package. If you get LiteSpeed server in VPS then it’s a good deal.

You may choose one of the hosts mentioned in this article to experience the best loading speed.

2. Use Cache Module

The cache module acts as a mediator between visitors and web servers. Cache modules save static files in their modules so that whenever visitors request any web content, it is directly served by the cache module instead of loading pressure on the main web server.

This helps in loading the website much faster. There are two free modules for Apache and NGINX which are very popular.

Both varnish and NGINX cache can be installed in Apache and NGINX web servers. Usually, those are provided by the host but if not you can ask them to install them. But make sure those are installed and configured properly.

Otherwise, this might even slow down your website. As per my personal experience, NGINX cache performs much better than varnish, and varnish cache creates so many problems if not configured correctly.

3. Use Reverse Proxy

A reverse proxy is an intermediate proxy server that handles all client requests as if it is the main server.

Whenever a client request happens, the reverse proxy server serves the content without bothering the main server.

The main difference between forwarding and the Reverse proxy is that, in the case of the Forwarding proxy, the proxy needs to be there at the client level. But in the case of reverse proxy, it sits on the server-side.

NGINX reverse proxy is very popular and can be installed in Apache and NGINX. So for those who are looking for a reverse proxy module, NGINX reverse proxy is a very good solution.

4. Enable GZIP compression

More than 90% of the website shows website contents in compressed format. If data is not compressed, it will take more time for a website to load which is annoying for many visitors.

You can enable GZIP compression by using a WordPress plugin but the same can be done by changing some settings at the server level.

How to enable GZIP compression in C Panel

  • Log in to C Panel
  • Go to Optimize Website under “software
  • Select desired compression option

5. Optimize Images

If you are using Apache or NGINX, then you can use the Page Speed module to optimize images at the server level. However, you can always optimize images by using WordPress plugins.

Page speed modules compress images and thus reduce website load time. Ideally, it can reduce image size by up to 50% by removing no visible image information and applying high-efficiency compression methods.

It also supports offering new image formats like WEP. If you allow the page speed module to change your HTML and CSS code then it reduces image size more and loads your website faster.

6. Use A CDN

A CDN ( Content Delivery Network) helps you by offering seamless speed for your website across the globe. CDN uses a bunch of servers in various cities of the world. Those servers copy your website content.

So whenever a visitor visits your website, the content gets delivered from the nearest server. Though this is the primary job of a CDN it does much more than this task nowadays.

7. Use HTTP/ 2 Or HTTP/3 protocol

HTTP/ 2 or HTTP version 2 protocol loads your website faster. At present, only 10 million website uses the HTTP/2 protocol. But these numbers are increasing and if you want to increase your website loading speed then you should use the HTTP/2 protocol.

If you are using shared hosting then you might see a straightforward setting to enable HTTP/2. In VPS or dedicated servers, you have to install the module manually depending upon your server type.

You can also enable HTTP/2 in Cloud flare CDN without bothering anything at the server level.

If you want to HTTP/3 or Quic then you need to use Lite Speed server as they have the support for HTTP/3 protocol

8. Use SSL

SSL ( Secure Security Layer) is a must nowadays if you want to speed up or rank your website. Google does not entertain any website nowadays without an SSL certificate installed.

SSL also helps in blocking not secure content and thus increases the website speed. For shared hosting nowadays all host provides free SSL.

For VPS and dedicated servers, you need to install the SSL certificate manually. If case you don’t want to install an SSL certificate at the server level, you can use Free SSL from Cloudflare.

9. Minify Codes

There are many server modules available that minify CSS, Javascript, and HTML codes to optimize the website.

Unnecessary codes are a big burden for speed. Magnifying codes help in removing those extra codes and loading your website faster.

Apart from minifying codes at the server level, you can also select the option in Cloudflare setting to minify Javascript, HTML, and CSS codes

10. PHP setting

The default PHP setting is not suitable to have a good loading speed for websites. Shared hosting does not allow for PHP setting changes. If you use a VPS or dedicated server then you can apply the below PHP setting to get the best out of your server.

memory_limit = 128M
suhosin.get.max_vars = 10000; = 10000;
