memory leak in this case:

  258.23MB 18.61% 39.29%   283.23MB 20.41%  net/textproto.(*Reader).ReadMIMEHeader

Important Note: If you aren't using gorilla/mux, you need to wrap your handlers with 
context.ClearHandler or else you will leak memory! An easy way to do this is to wrap the top-level mux when calling http.ListenAndServe:

http.ListenAndServe(":8080", context.ClearHandler(http.DefaultServeMux))
The ClearHandler function is provided by the gorilla/context package.

More examples are available on the Gorilla website.

Have you close the ctx.Body after used it?

@lunny 你指的是“defer ctx.Req().Body.Close()”吗？
