Magento Speed Optimization Techniques to Escalate Your Website’s Loading Speed

Impatience has been one of key reasons for customers to repel away from an eCommerce store. A customer expects to be impressed by the drop of a hat. Be it your website’s design or features, everything should be built focusing your end customer’s convenience. To find out what your customers exactly want is like looking for a needle in a haystack as there are many factors involved in it. However one factor that distinctly acts as a gateway between your eCommerce site and the customer is your site’s loading speed.

Being a website owner you need to be very watchful about your website’s loading speed. As per a study conducted, it was found that a loading speed greater than 7 seconds turns off a visitor. So an ideal loading time should be under 3 seconds. Although you might have hired the best brains to build your eCommerce website, yet as time rolls over you can witness a slackening in your website’s performance. So you need to be aware of some Magento speed optimization techniques that could work wonders for your website.

Tackling HTTP requests

HTTP requests are the biggest reasons for a website’s slowdown. These requests are a combination of images, JavaScript file and CSS files. In the server side the HTTP requests gets download as your site loads. When these requests start mushrooming, then your website’s speed tends to decelerate.

So what’s the solution? How can we reduce them?

In order to reduce these requests you need to try combining the above files as there is no point in deleting them. There are two ways to combine them. They are:

Using Sprite Image

The concept of sprite image is as follows “Rather than loading all the image files, you get to merge all these images and place them collectively under a single image. In spite of being in the same URL the location of these images can be distinguished from their background position. So there will be only one image file and when your website loads, the images will be retrieved separately from their background positions. By this way you get to reduce the image files effectively.

Merge JS and CSS files

Another method to reduce HTTP requests is to merge JS files separately and CSS files separately. Compared to the sprite image, this method is more straightforward. That too Magento platform makes this process even simpler. Admin can merge these files effortless from the backend.

For merging CSS files:

In the admin panel, select System -> Configuration -> Developer -> Merge CSS files

Follow the same for merging JS files:

Select System -> Configuration -> Developer -> JavaScript setting -> Merge JavaScript files

Augmenting PHP cache memory

When you add a new file, PHP code needs to track the path in order to retrieve the file. PHP gives you the option of using realpath cache, which caches the reference path of the file. By this way you will be able to reduce the disk lookups. In order to prove the improve the performance of realpath cache, you need to increase the value of the parameter realpath_cache_size. In general, if you do not include new files or change the paths often then it is advisable to increment the value of realpath_cache_ttl.

Making use of AJAX & image lazy loading techniques

AJAX represents a combo of programming tools like JavaScript, Microsoft Object, Extensible Markup Language, Dynamic Hyper Text Markup Language, etc. As per this technique, the contents in a website get updated only when a user commences an action. This is a great way of offering a speed service.

In the image lazy loading technique, when a user visits a site all the images above the fold will be loaded. When the user scrolls down, the images below the fold displays. By this method you can avoid an entire page reload.

Turning on Magento Cache

The Magento platform provides the users with a default cache in the backend known as the file system cache. Once you turn on this cache, your cached data will get stored in the Cache file. This cache turns out to be handy for website that receives limited traffic. Make sure you clean your cache files on a regular basis so as to serve users a fresh webpage.

Adjusting MySQL server

For an optimal performance, it is essential to configure your Magento website with MySQL database server. When your Magento site loads the queries are parsed and then executed. Fetching these queries from the disk is a time consuming process. By enabling MySQL’s built in parameter, query_cache_size, the queries get cached in the MySQL memory, resulting in a faster loading speed.

Tapping CDN

Content Delivery Network (CDN) is advantageous when it comes to reaching out to users from remote locations. Basically CDN is a collection of geographically distributed nodes also known as Edge servers. These nodes cache a copy of your webpage. When a user from a remote location visits your website, the node that is close to him serves the cached copy of the webpage, thereby reducing time latency.

Integrating Full Page Cache

Full Page cache is fantastic extension for improving your site’s loading speed. By installing this extension, Magento saves a copy of your webpage while delivering the site to a first time user. When the user revisits, the cached copy of the website will be displayed to the user. This extension will be effective in thwarting server downtime and will come handy during peak traffic period.

I am quite sure the above techniques will be very essential in improving your Magento site’s loading speed. If you are looking for Magento speed optimization services don’t hesitate to get in touch with us.
