Yes n8n can be faster than Make in some cases since it's self-hostable and cuts out the cold start delay Make scenarios sometimes have. But honestly the bigger win is how you structure the tool call itself the function tool approach you're thinking about is actually the right move, it gives you more control over the response timing. I'd love to walk you through the full setup, I do this kind of Vapi optimization work regularly. Want to jump on a quick call and I can get it sorted for you?
