How to use Preload and Prefetch to Improve Load Performance
Optimize Website Load Performance Using Preload and Prefetch
The preload value of the <link> element’s rel attribute lets you declare fetch requests in the HTML’s <head>, specifying resources that your page will need very soon, which you want to start loading early in the page lifecycle, before browsers’ main rendering machinery kicks in. This ensures they are available earlier and are less likely to block the page’s render, improving performance.
Here however, we will use a rel value of preload, which turns <link> into a preloader for any resource we want. You will also need to specify:
The path to the resource in the href attribute.
The type of resource in the as attribute.
<head>
<meta charset="utf-8">
<title>JS and CSS preload example</title>
<link rel="preload" href="style.css" as="style">
<link rel="preload" href="main.js" as="script">
<link rel="stylesheet" href="style.css">
</head>
<body>
<h1>bouncing balls</h1>
<canvas></canvas>
<script src="main.js" defer></script>
</body>
Prefetch
Prefetching is when content is downloaded in the background, this is based on the assumption that the content will likely be requested, enabling the content to load instantly if and when the user requests it. The content is downloaded and cached for anticipated future use without the user making an explicit request for it.

Why Use WordPress? What Can You Do With WordPress?
Can you use WordPress for anything other than blogging? To your surprise, yes. WordPress is more than just a blogging tool, and it has helped thousands of websites and web applications to thrive. The use of WordPress powers around 40% of online projects, and today in our blog, we would visit some amazing uses of WordPress other than blogging.
What Is The Use Of WordPress?
WordPress is the most popular website platform in the world. It is the first choice of businesses that want to set a feature-rich and dynamic Content Management System. So, if you ask what WordPress is used for, the answer is – everything. It is a super-flexible, feature-rich and secure platform that offers everything to build unique websites and applications. Let’s start knowing them:
1. Multiple Websites Under A Single Installation
WordPress Multisite allows you to develop multiple sites from a single WordPress installation. You can download WordPress and start building websites you want to launch under a single server. Literally speaking, you can handle hundreds of sites from one single dashboard, which now needs applause.
It is a highly efficient platform that allows you to easily run several websites under the same login credentials. One of the best things about WordPress is the themes it has to offer. You can simply download them and plugin for various sites and save space on sites without losing their speed.
2. WordPress Social Network
WordPress can be used for high-end projects such as Social Media Network. If you don’t have the money and patience to hire a coder and invest months in building a feature-rich social media site, go for WordPress. It is one of the most amazing uses of WordPress. Its stunning CMS is unbeatable. And you can build sites as good as Facebook or Reddit etc. It can just make the process a lot easier.
To set up a social media network, you would have to download a WordPress Plugin called BuddyPress. It would allow you to connect a community page with ease and would provide all the necessary features of a community or social media. It has direct messaging, activity stream, user groups, extended profiles, and so much more. You just have to download and configure it.
If BuddyPress doesn’t meet all your needs, don’t give up on your dreams. You can try out WP Symposium or PeepSo. There are also several themes you can use to build a social network.
3. Create A Forum For Your Brand’s Community
Communities are very important for your business. They help you stay in constant connection with your users and consumers. And allow you to turn them into a loyal customer base. Meanwhile, there are many good technologies that can be used for building a community page – the good old WordPress is still the best.
It is the best community development technology. If you want to build your online community, you need to consider all the amazing features you get with WordPress. Plugins such as BB Press is an open-source, template-driven PHP/ MySQL forum software. It is very simple and doesn’t hamper the experience of the website.
Other tools such as wpFoRo and Asgaros Forum are equally good for creating a community blog. They are lightweight tools that are easy to manage and integrate with your WordPress site easily. However, there is only one tiny problem; you need to have some technical knowledge to build a WordPress Community blog page.
4. Shortcodes
Since we gave you a problem in the previous section, we would also give you a perfect solution for it. You might not know to code, but you have shortcodes. Shortcodes help you execute functions without having to code. It is an easy way to build an amazing website, add new features, customize plugins easily. They are short lines of code, and rather than memorizing multiple lines; you can have zero technical knowledge and start building a feature-rich website or application.
There are also plugins like Shortcoder, Shortcodes Ultimate, and the Basics available on WordPress that can be used, and you would not even have to remember the shortcodes.
5. Build Online Stores
If you still think about why to use WordPress, use it to build an online store. You can start selling your goods online and start selling. It is an affordable technology that helps you build a feature-rich eCommerce store with WordPress.
WooCommerce is an extension of WordPress and is one of the most used eCommerce solutions. WooCommerce holds a 28% share of the global market and is one of the best ways to set up an online store. It allows you to build user-friendly and professional online stores and has thousands of free and paid extensions. Moreover as an open-source platform, and you don’t have to pay for the license.
Apart from WooCommerce, there are Easy Digital Downloads, iThemes Exchange, Shopify eCommerce plugin, and so much more available.
6. Security Features
WordPress takes security very seriously. It offers tons of external solutions that help you in safeguarding your WordPress site. While there is no way to ensure 100% security, it provides regular updates with security patches and provides several plugins to help with backups, two-factor authorization, and more.
By choosing hosting providers like WP Engine, you can improve the security of the website. It helps in threat detection, manage patching and updates, and internal security audits for the customers, and so much more.

How to Test Mobile App Performance: 3 Key Components - DZone Performance
You’ve probably interacted with an app on your phone or tablet that’s slow, takes a long time to load, freezes, or even crashes on you altogether.
Frustrating, right?
On the flip side, you can probably think of an app that you love to use because from day one, it’s never given you any trouble.
Or maybe you never paid any mind to an app that works quickly, because isn’t that how it’s supposed to be?
So, what causes one app to be crash-prone and another, fast, and reliable?
Whether an app has good or bad performance depends on three factors: the backend, the network, and the app itself running on the device.
A developer or mobile tester can measure the performance of an application in different scenarios.
For example, they can test for when there’s a concurrency of users on the app at the same time, on different devices (which vary in hardware resources and screen sizes), and multiple networks such as 3G, 4G, Wifi, and more.
The reality is that many variables affect the performance of a mobile application. Moreover, a user may have a very bad experience with your app and the cause might not even have anything to do with the code or its implementation.
But, by running performance tests for each of these three factors, you’ll be able to identify problems and optimize your app for the best user experience possible.
Keep reading as we’ll cover the different types of tests for each factor, what to measure, and what tools are available to help you along the way.
1st Mobile Performance Factor: The Backend
A mobile app’s backend architecture is generally based on an application server, a web server, and a database.
**When it comes to the backend, the things related to performance that are important to know when an app is under load are the server’s response times, database queries times, and the server’s resource usage. **
Using this information, it’s easier to detect issues such as:
- High server response times
- Bottlenecks or breakpoints in the database and application server resources
- Poor implementation of escalation policies
So what kind of tests are normally run to check the app’s backend performance? Load tests.
This is when you simulate load on the backend in different ways, whether it be through stress testing, peak testing, endurance testing, load testing, etc.
In general, the objective of these tests is to understand how the backend systems of an app behave and handle a certain volume of concurrent users.
Several tools allow you to load test your mobile app. The most commonly used ones include:
Apache JMeter – the number one open-source load testing tool
Gatling– a developer-friendly, open-source load testing tool with scripts written in Scala
BlazeMeter – a cloud performance testing platform that scales your JMeter or Gatling tests for a greater amount of concurrent users
2nd Mobile Performance Factor: The Network
With regards to the network that the device is connected to, there are two key things to measure: latency and bandwidth.
- Latency is the time that elapses when information is sent on the network (measured in milliseconds).
- Bandwidth is the maximum capacity (the amount of data) that can be transmitted through the network (measured in bits per second).
For mobile performance, the lower the latency and the higher the bandwidth, the better.
An app’s performance can vary depending on, for example, whether it’s connected to a 3G network or a 4G network, and unfortunately, this is beyond an app developer or tester’s control.
But, it is possible to incorporate the network during the mobile app performance testing process, simulating the different types of networks and measuring their impact on the response times, both on the server-side and the client-side.

Improve Your Site Performance with Load Balancing
The expectations of web users are increasing every year, and the search engines are also putting a lot of emphasis on ensuring that websites provide a seamless experience to their visitors. A lot of that has to do with making sure your site is easy to view on any device and convenient to navigate, but that’s just part of the equation — you also need to provide a fast browsing experience to all of your visitors, even on times when you have a sudden surge in traffic.
And that can pose a problem. Last year, Google started rolling out an algorithm that could punish websites that don’t load quickly, so those that won’t be able to adapt are doomed to see their rankings and traffic numbers decrease. Users are also placing higher importance on website loading speeds and will not hesitate to go to your competitors if your site is slow.
Luckily, there are ways to speed up your WordPress site and make sure that it can handle as much traffic as necessary. According to a report, loading speed and the general speed of the site in addition to user experience/interface made all the difference between making a conversion or having their bounce increase.
It was also important for them to increase speed for mobile devices. In general, for them, it was a hard compromise between deciding to remove important trust factors/seals and chat widgets verses improving speed. They chose the later.
Namely, you can use load balancing to help you make the most out of your hosting servers and optimize their performance in a way that makes the most sense in terms of user experience.
What is Load Balancing?
In essence, load balancing is the process of optimizing the use of your hosting servers to maximize performance and ensure fast loading times always.
Load balancing software solutions can direct incoming traffic to different servers, spreading out the visitors so that each server gets a fair share of the load and can perform at optimal levels.
By allocating the work between multiple servers, you can ensure that no servers get overloaded and that your website is always loading quickly for visitors from all over the world.
