**Issue Evaluation** Category: `type/enhancement` | Status: **Evaluated** **Feasibility:** Feasible **Scope:** `rmq.broker.logback.xml`, `TopicMessageType`, `RemotingHelper` **Compatibility:** No breaking changes. Three independent micro-optimizations, all well-motivated by JFR profiling: 1. **NopStatusListener** — Trivial config change, ~655 KiB saved. No downside. 2. **TopicMessageType.getMetricsValue() caching** — Standard enum constant caching pattern. Use `Locale.ROOT` for `toLowerCase()` as proposed. 3. **RemotingHelper eager evaluation** — `Map.get()` + null check instead of `getOrDefault()` with eager `String.valueOf()`. Classic hot-path optimization. Combined ~200-300 bytes/RPC saved with zero behavioral change. Clean, low-risk PR. --- *Automated evaluation by RockteMQ-AI* -- This is an automated message from the Apache Git Service.
