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 Light Speed server which is offered by many host in their shared hosting package.

Use Cache Module
Cache module acts as a mediator between visitor and web server. Cache modules save static files in their modules so that whenever visitor request for any web content, it is directly served by cache module instead of loading pressure on main web server. This helps in loading the website much faster. There are two free module for Apache and NGINX which is very popular.
Both varnish and NGINX cache can be installed in Apache and NGINX web servers. Usually those are provided by host but if not you can ask them to install my yourself. 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 problem if not configured correctly.
Use Reverse Proxy
Reverse proxy is an intermediate proxy server which handles all client request as if like it is the main server. Whenever a client request happen, reverse proxy server serves the content without bothering the main server. The main difference Forward and Reverse proxy is that, in case of Forward proxy, the proxy need to be there at client level. But in 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 reverse proxy module, NGINX reverse proxy is a very good solution.
Enable GZIP compression
More than 90% of website shows website contents in compress 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 setting 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.
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 module 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 support to offer new image formats like WEP. If you allow page speed module to change you HTML and CSS code then it reduce image size more and load your website faster.
Use A CDN
A CDN ( Content Delivery Network) helps you by offering seamless speed for your website across the globe. CDN uses bunch of servers in various cities of world. Those servers copies 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 but it does much more than this task now a days. If you want to know more about CDN and want to know about free CDN service then please read this article.
Use HTTP/ 2 protocol
HTTP/ 2 or HTTP version 2 protocol loads your website faster. At presents only 10 million website uses HTTP/2 protocol. But this numbers are increasing and if you want to increase your website loading speed then you should use HTTP/2 protocol. If you are using shared hosting then you might see a straight forward setting to enable HTTP/2. In VPS or dedicated sevrer you have to insall 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.
SSL ( Secure Security Layer) is a must now a days if you want to speed up or rank your website. Google does not entertain any website now a days without a SSL certified installed. SSL also helps in blocking not secure content and thus increase the website speed. For shared hosting now a days all host provides free SSL. For VPS and dedicated server you need to install the SSL certificate manually. If case you don?t want to install any SSL certificate at the server level, you can use Free SSL from cloudflare.
Default PHP setting is not suitable to have good loading speed of websites. Shared hosting does not allow for PHP setting change. If you use a VPS or dedicated server then you can apply below PHP setting to get best out of your server.
