Qwen 3.5 Thinking Anxiety

Hardware: 3060 / 12 GB | Qwen 3.5 9B

I've tried, making the system prompt smaller. Obviously, the paradox of thinking when it's not worth thinking is in effect but anyway. I've hijacked the prompt to create a reasoning within the reasoning to force immediate response but it's still not working as it takes 39.8 for a Hey and 2.5 seconds for the Stein or Quantum Mechanics.

I've read to put in the system prompt that it is confident, but does anyone have any other way.
