I actually captured max RSS size while running benchmarks as a rough approximation, but it's not exposed anywhere. If you go to the repo, you can run `./bench/compare -f rss_mb -lT bench/amd64/*.json` to see a table in the terminal. No big surprises there, Java engines (Rhino, Nashorn, GraalJS) are most memory-hungry.
