What are the most common performance problems with mobile and web applications?

The performance of mobile and web applications is critical to user experience and overall satisfaction. There are a number of common performance issues that can affect an application's load times, responsiveness and stability. Here are the most common performance issues and their causes:

1. Long loading times

• Causes: Large files (e.g. images, videos, scripts), unoptimized assets, slow server responses and excessive HTTP requests.
• Consequences: Users tend to leave the application early, resulting in a higher bounce rate.

2. Unoptimized images and media

• Causes: Use of high-resolution images without compression, lack of responsive design adjustments for different screen sizes.
• Consequences: Excessive loading times and data consumption, especially on mobile devices.

3. Poor server performance

• Causes: Insufficient server resources, slow database queries, non-optimized server configurations.
• Consequences: Delays in server response, which can lead to long loading times.

4. Non-optimized database queries

• Causes: Inadequate indexing, poorly designed queries, unnecessary data queries.
• Consequences: Slow data processing response times that negatively impact the overall user experience.

5. Excessive HTTP requests

• Causes: Too many scripts, stylesheets and images that need to be loaded.
• Consequences: Extended loading times and possibly a higher server load.

6. Weak Internet connection

• Causes: Users located in areas with weak network coverage, or mobile networks with limited bandwidth.
• Consequences: Slow loading times and frequent interruptions in the user experience.

7. Slow client page rendering

• Causes: Too many DOM elements, inefficient JavaScript operations and rendering issues.
• Consequences: Delays in displaying content that affect the user experience.

8. Lack of cache usage

• Causes: Lack of caching strategies that prevent frequently accessed data from being stored locally.
• Consequences: Repeated requests to the server that increase loading times.

9. Bad user interface

• Causes: Cluttered navigation, excessive animations and slow transitions.
• Consequences: Difficult interaction for the user and possible frustration.

10. Inefficient API integration

• Causes: Slow or unoptimized API queries that return large amounts of data.
• Consequences: Delays in loading data and interactions in the application.

11. Lack of optimization for mobile devices

• Causes: Lack of responsive design practices and non-optimized mobile user interfaces.
• Consequences: Poor user experience on smartphones and tablets.

12. Insufficient testing and monitoring

• Causes: Lack of regular performance reviews and testing under various conditions.
• Consequences: Issues that go undetected until they significantly impact the user experience.
