Desktop Application Desktop Application Performance & Optimization

Question 1

What is 'lazy loading' in desktop application performance optimization?

Accepted Answer

Loading resources or modules only when they are actually needed

Answer

Running the application at reduced CPU priority

Answer

Deferring updates until the system is idle

Answer

Caching data to disk to reduce memory usage

Question 2

Which technique reduces desktop application startup time by loading only essential components initially?

Accepted Answer

Splash screen with deferred initialization

Answer

Preloading all modules at launch

Answer

Increasing thread pool size

Answer

Disabling auto-save features

Question 3

What is 'memory leak' in a desktop application and why is it a performance problem?

Accepted Answer

When the application allocates memory that it never releases, gradually consuming more RAM

Answer

When the application reads data from the wrong memory address

Answer

When available system RAM drops below the application's requirement

Answer

When the application stores too much data in the Windows Registry

Question 4

What does 'multithreading' allow a desktop application to do?

Accepted Answer

Execute multiple tasks concurrently on different CPU cores or threads

Answer

Display multiple windows simultaneously

Answer

Handle multiple user accounts at the same time

Answer

Connect to multiple network servers in parallel

Question 5

What is 'caching' in desktop application performance?

Accepted Answer

Storing frequently accessed data in fast memory to avoid repeated expensive computations or reads

Answer

Saving user preferences to the hard drive

Answer

Backing up application data to a remote server

Answer

Compressing files before writing them to disk

Question 6

What is the purpose of 'profiling' a desktop application?

Accepted Answer

Measuring execution time and resource usage to identify performance bottlenecks

Answer

Recording user behavior for analytics

Answer

Setting up application themes and visual profiles

Answer

Configuring the application's network proxy settings
