5 Benefits of Using Varnish Cache for Magento

Looking for a caching technology that is incredibly fast? Well, you have come the right way. The Varnish Cache is a reverse caching proxy. Varnish Cache is a technology that reduces server load and improves website speed by providing some cached version of the pages from the website.

It will take a few milliseconds for the page to get delivered from the Varnish cache storage if a cached version of the request is available.

Sometimes response time depends on hardware too, but because loading a prepared response from memory is so much faster than having the web-server process everything on a disk, using Varnish is way faster than Magento’s cache mechanism.

In simple words, Varnish is an HTTP booster. You can also use this technology as a load balancer. All of which will result in increased performance of Magento Site. Varnish cache technology’s configuration language is known as VCL, which will be converted and compiled into C-code.

Varnish cache determines whether it can answer the request or not based on the cacheable assets obtained from the backend server. Varnish helps provide the most cost-effective solutions to traditional CDN services for web acceleration.

Top Benefits

Caching involves storing files or data ready for retrieval without the need to rerun all processes. It is essential to store the data in a memory or on a disk with a high reading speed to make the data available whenever needed. The need to download is excluded, and thus plenty of time is saved.

The browser will cache the assets like images & scripts when appropriate caching tools are used. And here, Varnish brings the caching of your site to the next level. Each time a visitor visits the website, a range of requests are sent to the server to load the page. Then the server starts looking for the files that are requested.

Varnish cache is like having a helping hand, which will watch out for duplicated requests already received before. After the first visit to the website, Varnish will create an exact copy of what is returned to the user. Lastly, Whenever the site is experiencing high traffic, it is equipped to cope with it.

An adverse effect of page loading time on the store’s ranking. And the user experience that affects the ranking.

So you need 3 components to get Varnish working:

  1. A server that is well configured (NGINX and Varnish ).
  2. The Varnish server-side configuration ( CLI).
