[r/LocalLLaMA] (Llama.cpp) In case people are struggling with prompt processing on larger models like Qwen 27B, here's what helped me out

Summary

A user discovered a significant performance improvement for Llama.cpp when processing prompts on larger models like Qwen 27B. By setting the `--ubatch-size` parameter to match their GPU's L3 cache size (in MB), they observed a substantial increase in prompt processing speed. This optimization made the models practically usable for tasks such as Claude code invocation on local hardware.
