Does using a framework like gin,martini reduces go 's performance if compared to pure go server code?

Is there a reduction in performance of a web app written in go if I use a framework like gin,martini instead of pure go code ?

I cannot answer this out of my own experience, but I hear people saying that in any real-world Web application, the HTTP router’s performance is usually the least thing to worry about.

I use gorilla/mux as router because is the most minimal. On the other hand because of the complexity of the code can be a very little difference in performance between various frameworks and simple http standard library based code, but i also think this is not worrying.
