The result after Just-In-Time compilation is highly optimized native code for the specific data the program is processing.īeing able to run the bytecode also enables more aggressive native optimization than a static compiler could safely use. This is the advantage of running the bytecode for a while before compiling it to native code: profiling information is automatically available. The code paths which are actually used will be more aggressively optimized, loops unrolled to exactly the right degree, and the hot instruction paths arranged to maximize I$ hits.Īll good stuff, yet it is almost never done because it is annoying to go through so many steps to build a binary.

The performance of essentially any program will improve if it is compiled, executed with profiling, and the results fed back into the compiler for a second pass. It's a huge win to use the same Java bytecode on multiple platforms and have it "just work."

I'll also add that maintaining a series of OS and architecture-targeted compilations of the same code base for every release can become very tedious. If any of the others are more important, go with bytecode. If speed is the only important factor, go native.

So when considering byte code vs native, consider which trade-offs you want to make between portability, security, size, and execution speed. Size: In the microprocessor world RISC is generally preferable Security: One of Java's virtues is its integration into the Web. Portability: Each kind of computer has its unique instruction Hank Shiffman from SGI said (a long time ago, but it's till true):
