Verified大模型推理的瓶颈往往不在算力而在内存带宽，GPU的算力利用率在推理阶段往往不到峰值的10%78% similarUnverified在超长上下文推理场景中，性能瓶颈往往不是算力而是KV缓存本身77% similarVerified移动端模型推理的速度瓶颈往往不在算力而在内存带宽76% similarUnverified神经网络推理的性能往往受限于内存带宽（memory-bound）而非算力（compute-bound）76% similarUnverified硬件性能定位入门级，CPU处理能力有限，开启大量防火墙规则或跑复杂队列时，千兆线速转发可能跑不满，对高吞吐+复杂规则有刚需应考虑更高端型号75% similar
