I ran into this also. I think I know what the problem is.
The CMake config in LLama.cpp is currently not optimizing for native architectures to fix an issue with MOE (https://github.com/ggerganov/llama.cpp/pull/6716). You'll get much slower performance with CMake on LLama.cpp right now. It took me a while to realize that Llama-cpp-python uses the CMake build pathway in LLama.cpp not Make.
An easy fix is to install llama-cpp-python from the repo, then edit extern/llama.cpp (where Llama-cpp-python downloads llama.cpp as a sub-repo) and modify the CMakeLists.txt to say set(LLAMA_LLAMAFILE_DEFAULT ON)
I gained a ton of performance that way.

@kinchahoy do you by chance know the tokens/sec performance before applying your fix and then after?
I'm doing kinda complex things but it took something that was taking 24s to encode down to 11-12s.
