help please？！！！

need some clarification. When using llama-cpp-python to start the server API with options --cache true --cache_type disk, I noticed that every time I query the model, it triggers
LlamaDiskCache.getitem. Does this mean that when using LlamaDiskCache in this way, the KV cache read/write completely bypasses GPU memory and system RAM, directly accessing the KV cache on disk? Wouldn't that be much slower?

I originally thought that the disk was only used for persistence, and that upon startup, the KV cache would be paged back into memory or GPU memory. Isn't that how it works?
