Playing around with splitting my project up into separate services, and
invoking via URLFetch between them. I'm seeing anywhere from a 20-22ms
latency on a very basic remote side side. I'm using Kotlin compiled down
to java8..... (the ping servlet is in java8...)...
So.. does ~20ms seem about right?
val fetchOptions =FetchOptions.Builder.doNotFollowRedirects()
val instanceHostname =getInstanceHostname("default", "1", "$serverNum")
val u = URL("http://$instanceHostname/ping";)
val req = HTTPRequest(u, HTTPMethod.GET, fetchOptions)
val timer = Stopwatch.createStarted()
val fetch = urlFetchService.fetch(req)
val rc = fetch.responseCode
timer.stop()
and then this in the /ping servlet
protected void doGet(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
PrintWriter writer = response.getWriter();
writer.println("Hello there from the backend");
writer.flush();
}
