💡 What: Introduced a sync.Pool for *bytes.Buffer in internal/runtime/executor/logging_helpers.go and replaced repeated instantiations.
🎯 Why: To eliminate repeated memory allocations and garbage collection overhead in the high-traffic request/response logging paths. Using bytes.Buffer is crucial here because strings.Builder.Reset() clears its underlying byte slice and capacity, rendering pooling ineffective, whereas bytes.Buffer.Reset() retains its capacity for actual reuse.
📊 Impact: Reduces memory allocations during log aggregation by reusing buffers, while preventing memory bloat via a strict maximum capacity check.
🔬 Measurement: Microbenchmarks indicate a measurable reduction in latency overhead when acquiring a pooled buffer versus allocating a new one repeatedly, leading to more stable latencies under concurrent load.
