curl_easy_perform() does the request in a fully synchronous manner and it
returns when the entire operation is done. That _can_ be very quick but it can
also be very slow. There's nothing you or libcurl can do about that.

You can use a timeout to stop slow operations, or you can switch to the multi
interface which is non-blocking and thus all (at least most) function calls
return very quickly.
