Tips & Tricks for Improving Website Performance with Caching

Speed matters! Whether you’re riding a motorcycle or loading a website! Those days are gone when people used to wait for several minutes to let a website load fully. In today’s scenario, your users will simply leave your website for the competitors, no matter how comprehensive and good-looking it is, if it takes forever to load. There are various factors that can affect your site’s performance and annoy your site’s users. Hence, instead of taking any chances, how about boosting your site’s performance and make it smooth for your visitors? And to do so, you may hire experts from the best website design company in India. However, before connecting with a web design company in India, you should know the basics of website performance and how you can improve it with caching.

What Is Website Performance, and What Role Does Caching Play in It?

Website performance stands for the speed and responsiveness of a website or web application. It is almost like a measure of how well a site loads, allows navigation, and responds to the users’ requests. Website performance is vital for many reasons. If a site performs well, it will offer a better user experience, which can drive better engagement and conversions. Further, website performance is a crucial metric for search engine rankings. A faster and more responsive website has greater chances of ranking higher.

Caching plays a vital role in website performance. It effectively reduces the amount of time and resources required to load a site. Generally, caching works by loading frequently accessed data into a temporary storage area (the browser’s cache or a server-side cache). If you request a page that has already been cached, you will get the cached version of the page instead of re-fetching the data from the server. This effectively reduces the amount of data that needs to be transferred and the total number of requests that need to be sent to the server. Thus, it results in faster page loading. Moreover, caching is also effective in reducing the server load and improve the overall performance of the website.

Understanding Different Types of Caching

In order to understand the connection between caching and website’s performance, it is important to know and explore the types of caching.

Browser Caching

It is a client-side caching technique that can be used to store frequently accessed resources, such as style sheets, images, and scripts, in the browser of the user. So, when a user sends request for the web page, the browser first analyzes whether the page is already cached or not. If it is already cached, it shows the cached version of the page instead of re-fetching the entire dataset from the server. This is an effective way to reduce the amount of data that needs to be transferred along with the number of requests, resulting in faster page load times.

If a developer sets a cache header, it informs the browser when to request new versions of the files or when to use the cached version. Remember, browser caching is not an alternative to server caching. It is effective in reducing the number of requests but does not follow the same path that server caching does to reduce the server load.

How to Implement Browser Caching

To implement browser caching, developers may set HTTP headers on the server side. Some of the most common headers are:

Cache-control: You can set cache directives like ‘public’, ‘private’, or ‘max-age’ to set the maximum time a resource can be cached.

Expires: You can set the date and time in case the resource is no longer considered fresh.

Etag: Developers also use Etag to enable a unique identifier for a specific version of a specific resource.

Last-modified: This header is used to refer the last time the resource was modified. Technologies like Apache and Nginx are suitable for setting these headers.

Server Caching

Server caching is a highly popular technique to store frequently accessed data on servers so that it can be quickly retrieved and served to clients. There is no need to regenerate or recalculate the data. This way, web developers can significantly reduce the load on the server and boost the performance and responsiveness of the website or web application. There are various server caches, such as memory caching, disc caching, and database caching. Server caching is useful for simple websites and large-scale web applications.

How to Implement Server Caching:

Using cache libraries or technologies like Redis, Varnish, Memcached, etc., developers can implement server caching for your website. This is an easy way to store and retrieve cached data. For professional website design services in India, experts prefer to use tools for database queries, rendered templates, and web service responses.

First, expert designers like professional website designers in India identify resources that need to be cached, set up a caching server, configure caching settings, add code to your application, and test and monitor caching.

CDNs to Boost Website Performance and Responsiveness

CDNs are basically a system of distributed servers that are deployed in multiple locations across the web. All these servers work together to offer fast and reliable delivery of web content. HTML, JavaScript, CSS, images, videos, etc., are some examples of web content that CDNs can deliver.

Remember, CDNs can improve site performance by caching and serving content directly from the server that is closest to the user. It is also known as “edge caching.” CDNs cache content on servers and reduce the distance that data needs to travel. Thus, it results in reduced latency and improved load times.

A content delivery network is also helpful to distribute a load of traffic across multiple servers. It can prevent outages and boost the overall stability of the website. CDNs also come with additional security features like SSL encryption, IP blocking, and DDoS protection.

Overall, CDNs are great tools for any website that needs fast and reliable performance for all users across the globe. They parallelize the download of resources to boost the page’s loading speed. By leveraging a wide network of servers, CDNs can help you speed up load times, enhance security, and improve stability.

How to Implement CDNs

To implement CDNs successfully, developers need to configure a set of edge servers that will cache as well as serve content to users. It is important to configure the origin server first. Once your server setup is done, you should configure your DNS to point to the CDN servers to direct the user to the nearest edge server. Furthermore, you must enable caching and invalidation rules to ensure that your content is always up to date.

How to Choose the Best Caching Plugin for Your Website?

The performance and speed of your site depend on the cache plugin you choose for your site. Consider a few factors to choose the right cache plugin:

Compatibility: You should make sure that the plugin is fully compatible with your site’s CMS and hosting environment.
Features: Look for features like page caching, browser caching, and the manifestation of CSS and JavaScript files.
Performance: Always try to choose a plugin that has already been tested and proven to be effective in improving the website’s performance.

Integration: If you are using CDNs or any other performance optimization tools, choose a plugin that can integrate with them.

Support: Check the level of support you will get from the plugin developer, including documentation, forums, and tutorials.

Conclusion

Caching is a powerful technique to improve website performance, speed, and responsiveness.
