A Race of Two Compilers: GraalVM JIT versus HotSpot JIT C2

Do you want to check the efficiency of the new, state of the art, GraalVM JIT Compiler in comparison to the old but mostly used JIT C2? The talk reveals how traditional Just In Time Compiler (e.g. JIT C2) from HotSpot/OpenJDK internally manages runtime optimizations for hot methods in comparison to the new, state of the art, GraalVM JIT Compiler on the same source code, emphasizing all of the internals and strategies used by each Compiler to achieve better performance in most common situations (or code patterns). For each optimization, there is Java source code and corresponding generated assembly code in order to prove what really happens under the hood.
