9 strategies to improve speed of your app

The longer an app takes to load, the less satisfied the user is. Let’s look at these few numbers to understand how mobile app loading time is crucial to your app’s popularity.

• 3% of users don’t want to wait more than a second to view the page.
• 16% of users don’t like to wait more than 1-5 seconds,
• 30% of users are able to endure a wait 6 to 10 seconds,
• 16% users with the patience to wait 11 to 15 seconds.

So how do you speed up the loading of your application?

Caution: Some of these measures are delicate to implement, do not hesitate to offer you the services of a professional on Codeur.com

1. Use a CDN

A distributed server system for delivering Web pages from multiple geographic locations is called a content delivery network (CDN).
A CDN allows you to reach an audience that is not in the vicinity of your web server. Using a CDN allows you to reduce the bandwidth used on your server, and reduce the risk of slowdowns due to heavy traffic.
CDNs are generally used for static files such as Javascript, CSS and images.

2. Optimize the images

Images and other graphic elements consume a lot of space in an application. Even if you use a CDN, image optimization should not be neglected.
Compress and reduce the size of images as much as possible while making sure that the image quality is not attenuated.

3. Use lightweight code

It is advisable to remove all unnecessary code from your application. Make sure that CSS, JavaScript and HTML files are kept compact so that they can be easily accessed at runtime.

Code should be clean and uncluttered, and should be loaded before the page hits the screens. Messy, bulky code slows down the speed of a mobile application.

4. Work on the speed of the server

Working in the IT industry, you must have heard hundreds of times that “the server is down” or that it is “slow”. This happens when the server is overloaded by the frequency of requests.

5. Minimize HTTP requests

Every request made to the server to retrieve a response, whether it is a file, an image, or a video, is considered an HTTP request. These HTTP requests consume nearly 80% of the application’s load time.
Their number is limited (between 4 and 8 simultaneous requests): it is useless to explain that the less HTTP requests there are, the faster the application will perform. So how to minimize HTTP requests?

• By combining the : Combine CSS and JavaScript files into a single file and dramatically reduce the number of requests to the server.
• Reduce the number of images: Analyze your page and try to eliminate unnecessary images, which will help reduce the number of HTTP requests. In addition, this will beautify the appearance of the application and allow you to showcase the well-processed content you have written on the page.

6. Update the application regularly

To the question of how to speed up the loading of your mobile app, the first answer should be that you should update it regularly. Regardless of the platform you built your app on, you need to make sure it’s running on the latest version of that platform.
Outdated platform versions can cause serious problems in the long run. In addition, they have limited platform support and pose a security threat to the application.
Also, keep users informed about updates and releases, so they can update the application when needed.

7. Check that there is not too much data

An application collects and stores a large amount of data. If this data collection is not well managed, it affects the speed of the application. The solution to overcome this problem is to compress the data received by the application.
This data includes the application code, HTML tags, images and videos. It is usually transferred in an uncompressed form, so you need to work on compressing this data. By compressing the data, you can expect consistent application performance and high speed.

8. Enable caching

Caching consists of storing data locally. Caching allows the page to be loaded without making a new HTTP request to the server. Users can access the data instantly without waiting for the server to respond.

9. Reduce the number of animations

The main logic behind using animations in mobile apps is to improve the user engagement rate in the app. Moreover, it makes the navigation part interesting. However, it is good to limit the number of animations. This does not mean that your application will be monotonous, but keep in mind that often “less is more”.
