If you're quoting that paper's numbers, or re-measuring its programs, please also be aware of https://blog.golang.org/profiling-go-programs which says: "At Scala Days 2011, Robert Hundt presented a paper titled Loop Recognition in C++/Java/Go/Scala. The paper implemented a specific loop finding algorithm... By using Go's profiling tools to identify and correct specific bottlenecks, we can make the Go loop finding program run an order of magnitude faster and use 6x less memory. (Update: Due to recent optimizations of libstdc++ in gcc, the memory reduction is now 3.7x.)" That blog post goes on to show a C++ program that solves the same problem, but on Russ' hardware, is 8x faster than the original paper's C++ program. The 2020 JVM may very well be better than the 2011 JVM, but I don't think this paper (even with the 2020 JVM) settles the GC (e.g. Java) versus C++ argument. -- You received this message because you are subscribed to the Google Groups "golang-nuts" group.
