What is the performance impact of AOT and JIT compilation?

What is the performance impact of AOT and JIT compilation?

AOT (Ahead-of-Time) compilation can lead to faster startup times and reduced runtime overhead, while JIT (Just-In-Time) compilation optimizes performance during execution but may introduce delays at startup.

Can you explain how AOT and JIT affect memory usage?

AOT typically uses more memory upfront since it compiles everything before execution, whereas JIT may use less memory initially but can increase memory usage during runtime as it compiles code on the fly.

Which one is better for mobile applications?

AOT is often preferred for mobile applications due to its faster startup times and lower runtime overhead, which is crucial for performance on resource-constrained devices.

Are there any scenarios where JIT is more beneficial?

Yes, JIT can be more beneficial in scenarios where applications require dynamic code execution or frequent updates, as it can optimize performance based on actual usage patterns.
