Just a couple days ago I learned about ninfer (https://github.com/Neroued/ninfer) and on RTX 5090 I can now get ~200 tok/s and over 400 tok/s on concurrent requests which is plenty fast for a local model of this strength.
Even without ninfer I would get over 80 on LM studio with default settings, so it should be noticeably more on 6000. You might want to try different a different inference engine or settings.
