Explore the intricacies of runtime and compile-time optimizations in Java and C++ in this 52-minute conference talk from Devoxx. Delve into a comprehensive research study comparing Just-In-Time (JIT) compiler optimizations in HotSpot/OpenJDK with Ahead-of-Time (AOT) optimizations performed by LLVM Clang in C++. Gain valuable insights into the performance implications and trade-offs between these two optimization approaches, enhancing your understanding of compiler technologies and their impact on program execution.
