> We are replacing the JDK implementation with our own, and I feel JIT might be able to optimize on the JDK default method, and the benchmark might have different result in different environment. If some new optimizations are introduced in the future java version, we won't be able to get that. Do you think this method might be slower in certain environments? As far as I am aware there is no Java or C++ compiler capable of performing this transformation, as simple as it is. It's possible that this will be treated with a vectorized intrinsic (the same trick is scalable) in the future, but Pinot doesn't run on JDK16 without adding a lot of `--add-opens` so shall we cross that bridge when it exists? -- This is an automated message from the Apache Git Service.
