Interesting, but possibly outdated by now. E.g. they compare against a seven-year-old version of ZGC. Back then, ZGC was not only not generational, but did some scanning during a stop-the-world pause (e.g. of stacks, but not only stacks). These days, even the objects directly on the stack aren't scanned at all during a STW (a pause is only used as an efficient thread synchronization mechanism; no GC work, including the scanning of any object is done in a STW).
