What are the performance differences between JIT and AOT compilation?

What are the performance differences between JIT and AOT compilation?

JIT (Just-In-Time) compilation compiles code at runtime, which can lead to faster execution for dynamic applications. AOT (Ahead-Of-Time) compilation, on the other hand, compiles code before execution, resulting in faster startup times and potentially better optimization.

Can you give examples of when to use JIT or AOT?

Sure! JIT is often used in environments like Java and .NET where runtime optimizations are beneficial. AOT is commonly used in mobile applications, like those built with Flutter, to improve startup performance.

What are the trade-offs between JIT and AOT?

The trade-offs include JIT's flexibility and runtime optimizations versus AOT's faster startup and lower memory usage. JIT may lead to longer execution times initially, while AOT can result in larger binary sizes.

How do JIT and AOT affect debugging?

JIT can make debugging easier since it allows for dynamic code changes, while AOT can complicate debugging due to the pre-compiled nature of the code.
