vLLM is known for its PagedAttention technology, which significantly improves throughput by efficiently managing the KV Cache; SGLang, through RadixAttention and more aggressive prefix cache reuse, often achieves lower latency in multi-turn dialogue and long-context scenarios.

UnverifiedvLLM and SGLang are service-oriented inference frameworks that support technologies such as Continuous Batching and PagedAttention to maximize concurrent throughput.76% similarUnverifiedWhat local inference frameworks can do is optimize KV cache management (such as paged attention and prefix caching), so that long conversations are not interrupted by running out of VRAM, thereby remaining stable in multi-turn scenarios.74% similarUnverifiedvLLM implements Automatic Prefix Caching, and SGLang supports fine-grained cache reuse based on RadixAttention.72% similarUnverifiedPagedAttention is a memory management mechanism introduced by the vLLM inference engine that splits the KV cache into fixed-size blocks allocated on demand, raising memory utilization from about 60% to over 90% and supporting multiple requests sharing base weights.72% similarUnverifiedBuilding long-context applications should prioritize using mature inference frameworks with built-in paged KV caching (such as vLLM and SGLang) rather than reinventing the wheel.70% similar
