Hugging Face model download adds 30s to GPU startup time

By PulseAugur Editorial · [1 sources] ·

A test on a Runcrate L40S GPU revealed that downloading a 7B model from Hugging Face adds approximately 30 seconds to the initial startup time. When the model weights were already cached locally, the time to first token was reduced from 48-55 seconds to 18-19 seconds. The process of loading the model into GPU memory took about 14 seconds regardless of whether it was a fresh download or from a local cache, indicating that disk read speed was the bottleneck for this operation.

IMPACT Optimizing model loading can significantly reduce inference latency for frequently started GPU instances.

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

    <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…
