loongsuite-site-bootstrap: started successfully (OpenTelemetry auto-instrumentation initialized). "**Issue Evaluation**\n\nCategory: `type/enhancement` | Status: **Confirmed**\n\nVerified against the current codebase on `develop` branch.\n\n**Analysis:**\n- `ProxyContext#value` is initialized as `new HashMap<>()` (default capacity 16, resize threshold 12 at 0.75 load factor).\n- `ContextVariable` defines 10 well-known keys, all typically populated per request.\n- With interceptors/plugins adding more entries, the map reliably crosses the threshold of 12 on every request, triggering a resize on the hot path.\n\n**Assessment:**\n- **Feasibility:** Straightforward \u2014 single-line change with no behavioral impact.\n- **Scope:** `proxy/src/main/java/org/apache/rocketmq/proxy/common/ProxyContext.java` only.\n- **Compatibility:** No breaking changes. The proposed capacity of 64 (threshold 48) provides comfortable headroom.\n- **Impact:** Eliminates a deterministic rehash on every gRPC/Remoting request. Negligible memory overhead (~256 bytes per context).\n\nThis is a valid and wel l-motivated optimization. The suggested approach (initial capacity = 64) is reasonable.\n\n---\n*Automated evaluation by oss-sentinel-ai*\n" -- This is an automated message from the Apache Git Service.
