Comment utiliser Java sur Google App Moteur sans dépasser les quotas minimes?

Un code Java très simple à l'intérieur d'un servlet Doget () obtient plus d'une seconde heure de la CPU sur GAE. J'ai lu une documentation liée au quota et apparemment je ne fais rien de mal.

@SuppressWarnings("serial")
public class R2CComingSoonSiteServlet extends HttpServlet {

private static final Logger log = Logger.getLogger(R2CComingSoonSiteServlet.class.getName());

public void doGet(HttpServletRequest req, HttpServletResponse resp)
        throws IOException {
    //The two lines below will get the CPU before requesting User-Agent Information
    QuotaService qs = QuotaServiceFactory.getQuotaService();
    long start = qs.getCpuTimeInMegaCycles();

    //Request the user Agent info
    String userAgent = req.getHeader("User-Agent");

    //The three lines below will get the CPU after requesting User-Agent Information 
    // and informed it to the application log.
    long end = qs.getCpuTimeInMegaCycles();
    double cpuSeconds = qs.convertMegacyclesToCpuSeconds(end - start);
    log.warning("CPU Seconds on geting User Agent: " + cpuSeconds);

    userAgent = userAgent.toLowerCase();
    if(userAgent.contains("iphone"))
        resp.sendRedirect("/mobIndex.html");
    else
        resp.sendRedirect("/index.html");} }
