Multiple choiceHardchapter-14-curatedpremiumperformance-tuningstop-the-world-pauses
Answer and explanation
Correct answer
A. ZGC performs concurrent compaction to avoid 'Stop-The-World' pauses.
Why
ZGC's major advantage is its ability to perform concurrent compaction, which means it can relocate objects without requiring significant 'Stop-The-World' pauses, unlike G1GC which needs such pauses for compaction.
