Memory Management · interview question
Why is simply increasing -Xmx a weak first response to an allocation-churn problem?
Multiple choiceMediumchapter-14-curatedpremiummemory-managementout-of-memory-errors
Answer and explanation
Correct answer
A. Because churn is about object creation and collection rate, not just retained heap size
Why
If the service keeps allocating and discarding too many temporary objects, a bigger heap may only delay collections. The core problem is still hot-path churn and GC overhead.
