As I pointed out long ago on stackoverflow the benchmark games are seriously flawed and should not be used for language performance comparisons.
As a simple example, look at binary trees. In all of the “fast” implementations, they resort to specialized memory pools that wouldn’t be useable in a highly concurrent system. The Go and Java versions use off the shelf memory management so the code complexity comparisons are not even close. I’m sure you could replicate the performance using off heap structures in Go/Java but who would want to? > On Mar 6, 2019, at 7:17 AM, Haddock <ffm2...@web.de> wrote: > > Benchmarks are always limited, I know.
