Small point of order: bit slower might not set expectations accurately. You noted in a previous post in the same thread[^1] that we'd expect about a 1 minute per 10K tokens(!) prompt processing time with the smaller model. I agree, and contribute to llama.cpp. If anything, that is quite generous.

I don't think the time grows linearly. The more context the slower (at least in my experience because the system has to throttle). I just tried 2k tokens in the same model that I used for the 120k test some weeks ago and processing took 12 sec to first token (qwen 2.5 32b q8).

  • Hmmm, I might be rounding off wrong? Or reading it wrong?

    IIUC the data we have:

    2K tokens / 12 seconds = 166 tokens/s prefill

    120K tokens / (10 minutes == 600 seconds) = 200 token/s prefill

  • > The more context the slower

    It seems the other way around?

    120k : 2k = 600s : 10s
