Agentic Inference Turns KV Cache Management Into a Scheduling ProblemThis deep dive frames tool-using LLM serving as a stateful KV-cache scheduling problem. It traces what happens when agents wait on tools—GPU residency, eviction, restoration, and prefill recomputation—and compares the resulting latency and throughput tradeoffs.🔗 contextosai.com#llm_inference #kv_cache #agents

Go 1.27 Specializes Small Allocations for Up to 30% Faster mallocsGo 1.27 specializes allocation paths for objects under 80 bytes, emitting span-class-specific malloc functions while retaining generic fallbacks. Small allocations improve by up to 20–30%, although whole-program gains are around 1% and constrained by instruction-cache tradeoffs.🔗 go.dev#go #runtime #performance
