Is my question fit for Stack Overflow?

I recently posted a question and it got some downvotes, so I reviewed the Stack Overflow help center and didn't seem to find anything that could be the reason my question was downvoted.

My question:Will using synchronous functions in an async project have any performance drop?

The material I reviewed:

https://stackoverflow.com/help/on-topic

1. My question was a specific programming problem, so I think I'm fine there
2. Not for debugging. Not for a simple error. Not a recommendation. Nothing about hardware. Nothing about legal things. Nothing about networking.

https://stackoverflow.com/help/dont-ask

1. Not every question will be equally valid
2. My answer isn't in the question
3. It's not an open hypothetical question.
4. Although it's a subjective question, its answers will most likely have the following
   • It will explain if using Pymongo in an async project will cause issues
   • Won't have short answers
