Multiple choiceMediumchapter-14-curatedpremiumperformance-tuningstop-the-world-pauses
Answer and explanation
Correct answer
A. Sub-millisecond pause times

ZGC is designed to provide sub-millisecond pause times by performing most operations concurrently with the application threads. This reduces the impact of garbage collection on application performance, especially under high load.
