Please answer these questions before submitting your issue. - Why do you submit this issue? - [ ] Question or discussion - [ ] Bug - [ ] Requirement - [X] Feature or performance improvement ___ ### Requirement or improvement - We face full gc issue lately，I dump the heap and found that PersistenceTimer occupied most of heap memory  - I looked into code, found that PersistenceTimer use one thread persistence Metrics synchronously and periodically（5s） - When peak traffic arrives, persistence time explode sharply and next persistence will delay (scheduleWithFixedDelay), which cause Metrics increase next time. It is vicious circle.  - I want to konw, why metrics need to persist synchronously, can we just persist like record -- This is an automated message from the Apache Git Service.
