Thunderbolt 5 连接问题困扰 Llama.cpp RPC 基准测试

一位用户详细介绍了他们使用两台机器通过 RPC 运行 Llama 模型进行基准测试的经验,重点关注不同网络链路的性能差异。用户遇到了 Thunderbolt 5 连接的重大问题,发现它在基于 DMA 的传输方面不可靠,最终选择了 USB 10Gbps 连接。基准测试显示,在延迟和吞吐量方面,Thunderbolt 5 的性能不如标准的 5GbE 连接,而 USB 10Gbps 的性能略好,但存在一些特定模型的例外情况。测试涉及六种不同的模型,并探讨了单流和并发请求处理,并指出在高并发级别下,内存溢出成为更密集模型的瓶颈。 AI

影响 强调了高效本地 LLM 部署的潜在硬件瓶颈。

    我购买了 Thunderbolt 5 却得到了 USB4 40G:跨三个链接和六个模型的两台机器 llama.cpp RPC 设置重新基准测试

    <p>This post is a follow-up to my previous benchmark. It tests six models across three links — 5GbE, "fake TB5," and USB 10GbE — comparing how link speed affects performance.</p> <p>I'd originally planned to test only TB5, then move on to other things. Buy a cable, plug it in, me…
