25x inference performance on NVIDIA GB300 NVL72
25x inference performance improvement on NVIDIA GB300 achieved through SGLang's RadixAttention mechanism, which optimizes KV cache reuse by indexing prefixes in a radix tree to eliminate redundant computations. For agent workloads with 80% prefix overlap, this approach combined with chunked prefill and continuous batching delivers significant throughput gains by computing shared system prompts and context only once instead of repeatedly.
