Hi

has anyone else a slowdown when using @com.google.inject.Inject into a
resource?

In my ServletModule I'm filtering with
com.sun.jersey.guice.spi.container.servlet.GuiceContainer:


  @Override
  protected void configureServlets() {
  Map<String, String> params = new HashMap<String, String>();
    params.put(PackagesResourceConfig.PROPERTY_PACKAGES, "com.foo");
    filter("/*")
    .through(com.sun.jersey.guice.spi.container.servlet.GuiceContainer.class,
    params);
    }

I've setup a resource like this to eliminate service use but leave in
the Injector.

 @Path("b")
 public class Bench
 {
    private URLMinifier _urlMinifier;

    @com.google.inject.Inject
    public Bench(URLMinifier urlMinifier) {
        _urlMinifier = urlMinifier;
    }

    @GET
    @Path("{urlslug}")
    @Produces("text/plain")
    public Response getURL(
      @PathParam("urlslug") String urlslug,
      @Context ServletContext context)
    {
        String test = "http://example.org/bar";
        return Response
                .status(200)
                .header("Content-Length", test.length())
                .entity(test)
                .build();
    }
 }

what I'm seeing is severe slowdown (drop to ~40rps) when the @Inject is
present. If I remove it Jersey zips along.
