Java Bytecode is similar to WASM, opcode wise. Bytecode purposely omits many instructions that can be done with equivalents to fit the whole ISA in single byte instructions. WASM is similar for the same reason, code density. The main difference in Bytecode/WASM is memory model and branching support. But you could say that both are equivalent to 80's ISA's. Precompiled Java is closer to WASM than many would like to admit, so I expect performance to be similar in the long run. This isn't so bad, Java reaches over half native speed on many benchmarks. It's amazing that we'll be able to run untrusted code so quickly
