The major issues that make your mobile app slow

The major issues that make your mobile app slow are:

Your app is obsolete and not supportive: make sure that the app is designed on the latest version of the Operating System.

Sluggishness of the server speed: Can't connect to the server error, means the back-end infrastructure is slow AKA the server is slow or it has become overloaded.

• The server may slow down due to the multi-tiered infrastructure on which most modern-day applications run.
• You may have problems accessing files from the disk, running the application code, or communicating instantly with users over the chat, and so on.

Encrypted connections are not optimized: SSL/TLS connections provide encryption for data in-transit and are crucial from the app development point of view. Can create problems if left unoptimized, which the encrypted connections result in decreased performance of the app.

• A handshake is required each time you open a new connection, which affects the speed.
• Problems are faced during the encryption of data on the server and decryption on the client-side.

Chatty conversations: occurs when the client makes several requests to conduct a transaction on behalf of individual operations within the application.

Faulty library and software development kit: Issues with third-party libraries

• Allowing images to be loaded into the app by using the Picasso and Glide libraries
• Simplifying the communication process between different parts of the application by using the Eventbus library
• Retrofit, an Android-based library that helps arrange the API calls in a project

App is overcrowded with data: The lossless method and the second is lossy compression.

• Lossless compression: In this method, the developer can restore the file to its original size and there is no loss of data when the file is not compressed. This type of data compression technique is used when reducing the size of text and spreadsheet documents.
• Lossy compression: In the second approach, you’re actually removing the data from the app, which is usually not really noticable. This data compression method is used to compress the size of video, audio, and graphic files.

Network latency: Application is making a query to a non-existent primary DNS server and gets no reply, it will try the second DNS server, this slows down the application speed.
