Why is WeChat applet loading extremely slow?

The reason why the WeChat mini program is extremely slow to load may be network problems, server load, excessive size of the mini program, slow loading of images, long JS code execution time, slow loading of third-party plug-ins or components, other factors, etc. . Detailed introduction: 1. Network problems. The loading speed of WeChat applet is affected by network conditions. If the network connection is unstable or the network delay is high, it may cause the applet to load slowly. You can try to switch to a more stable network environment, such as using Wi-Fi connection, or check network settings and signal strength; 2. Server load, etc.

The operating system of this tutorial: ios16.6 system, WeChat version 8.0.41, iphone14 computer.

Slow loading of WeChat mini programs may be caused by a variety of reasons. Below I'll cover some common causes and solutions.

1. Network problems:

The loading speed of WeChat applet is affected by network conditions. If the network connection is unstable or the network latency is high, it may cause the applet to load slowly. You can try switching to a more stable network environment, such as using a Wi-Fi connection, or check the network settings and signal strength.

2. Server load:

When the number of visits is large or the server load is high, the loading speed of the mini program may slow down. This is because the server needs to handle more requests, resulting in delayed response times. At this time, you can try to use the mini program during off-peak hours, or contact the developer or operator of the mini program to understand the server load.

3. The mini program is too large:

If the file size of the mini program is too large, the loading speed may slow down. Especially under poor network conditions, large files can increase download time. In order to speed up loading, it is recommended to optimize the mini program, including compressing and merging files, reducing unnecessary resources and code, etc.

4. Slow image loading:

If the mini program contains a large number of images and the size of these images is large, the loading speed may be affected. You can try compression, optimization, and lazy loading of images to reduce image size and loading time.

5. The JS code execution time is too long:

If the JS code execution time of the mini program is too long, the loading speed may be slowed down. This may be because the code is logically complex, computationally intensive, or has performance issues. In order to improve loading speed, it is recommended to optimize JS code, including reducing unnecessary calculations, optimizing loops and recursion, etc.

6. Third-party plug-ins or components load slowly:

If third-party plug-ins or components are used in the mini program, and the loading speed of these plug-ins or components is slow, it will also affect the overall Loading speed. When choosing to use plug-ins or components, it is recommended to choose plug-ins or components with better performance and faster loading speed.

7. Other factors:

In addition to the above reasons, there are some other factors that may affect the loading speed of the mini program, such as device performance, system version, mini program version, etc. You can try to update your device and applet to the latest versions, or try loading the applet on other devices to troubleshoot device and system issues.

If you have tried the above methods and still cannot solve the problem, you may need to consider the following possibilities:

- There are some problems with the mini program itself, and you may need to contact the developer or operator of the mini program. Report questions and ask for help.

- There are some problems on the WeChat platform, and you may need to wait for WeChat official solutions or updated versions.

It should be noted that the loading speed of mini programs is affected by many factors, and different mini programs may have different problems and solutions. If the problem persists and affects the user experience, it is recommended to contact the developer or operator of the mini program for professional technical support and solutions.
