Hey,

I am trying currently trying to use the http_listener. While it does work, I am suffering from massive performance issues / hanging.
Some HTTP requests I throw against the http_listener are handled immediately, while others take up to 20 seconds. The request that hang are usually the first request made, as well as requests that are being made after a few seconds of no requests.

Here's an example of how I register the handlers and start the listener loop:

void HttpListener::registerMethodHandlers() {
    mListener.support(methods::POST, &HttpListener::spawnRequestHandler);
    mListener.support(methods::GET, &HttpListener::spawnRequestHandler);
    mListener.support(methods::PUT, &HttpListener::spawnRequestHandler);
    mListener.support(methods::DEL, &HttpListener::spawnRequestHandler);
}

void HttpListener::startLoop() {
        mListener.open().wait();
}

void HttpListener::spawnRequestHandler(http_request request) {
    std::thread handlerThread([request](){
        HttpRequestPreHandler handler(request);
        handler.handleRequest();
    });
    handlerThread.detach();
}

I am using cpprestsdk version v2.10.16 compiled on Arch.

I have not included the functions that are being called inside spawnRequestHandler in the code sample because the delay happens before spawnRequestHandler is called.
