English(EN) Fresh Hugging Face download vs local cache: time to first token for a 7B model on a Runcrate L40S

Hugging Face 模型下载使 GPU 启动时间增加 30 秒

作者 PulseAugur 编辑部 · [1 个来源] · 2026-10-29 03:24

在 Runcrate L40S GPU 上进行的测试显示，从 Hugging Face 下载一个 7B 模型会使初始启动时间大约增加 30 秒。当模型权重已缓存到本地时，首次 token 时间从 48-55 秒减少到 18-19 秒。无论是在线下载还是从本地缓存加载，将模型载入 GPU 内存的过程大约需要 14 秒，这表明磁盘读取速度是此操作的瓶颈。 AI

影响优化模型加载可以显著减少频繁启动的 GPU 实例的推理延迟。

Hugging Face 最新下载与本地缓存对比：Runcrate L40S 上 7B 模型首次 token 时间

<p>How long does a GPU machine sit idle before a 7B model answers its first request, and how much of that is the download? I rented one L40S on Runcrate today (2026-10-29), timed every phase of starting Qwen2.5-7B-Instruct from a fresh Hugging Face download and from a copy alread…
