This just isn't true. There's many Java ports of C/C++ applications and benchmarks are usually within 30%.

- coldtea 9y agoFor the easy tasks. Try a CPU heavy C/C++ app -- like an audio/video editor, number crunching of any kind, etc.
- forgotpw1123 9y agoLike I said, the major exception is SIMD instructions. AV and heavy math are a tiny fraction of applications. For these you can use JNI. There is precedent for this in Netty where they use a native poll mode driver and everything else Java, and it performs about as fast as pure C code on Techempower benchmarks
