**Issue Evaluation**
Category: `enhancement` | Status: **Evaluated**
**Feasibility:** Feasible
**Scope:** `common` module (`ExtraInfoUtil`)
**Compatibility:** No breaking changes — internal parsing optimization
The analysis is accurate. `ExtraInfoUtil` POP info parsing currently:
- Allocates `String[]` via `split\(","\)` for fields that are only iterated
once
- Boxes primitives (`Long`, `Integer`) in return types where callers
immediately unbox
Returning primitives (or a small record/POJO with primitive fields)
eliminates the boxing overhead and reduces GC pressure on the POP consumption
path.
The proposed benchmark methodology (broker-side CPU sampling + allocation
profiling under sustained POP load) is appropriate for quantifying the
improvement.
