OpenClaw with a DGX Spark

I am new to OpenClaw and am interested in local llm options. I currently run OpenClaw on my MacBook which connects to vllm on my DGX which serves glm-4.7-flash. It’s terribly slow. Even simple interactions can take 10+ seconds for a response. Sometimes on the order of minutes.

I’m a developer, but the AI space is new to me. I assume others have tried a local llm on the dgx with openclaw. I am trying to align my expectations. Is it just a slow terrible user experience unless you use frontier models? Or do i need to tune things to get a reasonably snappy claw? I’m open to exploring tuning options but if there isn’t a point then i should cut my losses now
