With Java, the issue is that each allocated object carries significant memory footprint, as result total memory consumption is much higher compared to C++: https://benchmarksgame-team.pages.debian.net/benchmarksgame/...

The benchmarks game shows memory use with default GC settings (as a way to uncover space-time tradeoffs), mostly for tiny tiny programs that hardly use memory.

Less difference — mandelbrot, k-nucleotide, reverse-complement, regex-redux — when the task requires memory to be used.

Less with GraalVM native-image:

yes, I referred to benchmarks with large memory consumption, where Java still uses from 2 to 10(as in binary tree task) more memory, which is large overhead.
