Wildfly number of client connections JAX-RS/Resteasy

[paulie-paulie]

I am running WildFly 10 (Final release) and I have a very simple JAX-RS server application. It has only one test endpoint, which waits for one second and then returns HTTP OK status.

@Path("/test")
public class TestEndpoint {

@GET
@Produces("application/json;charset=UTF-8")
public Response get() {
   try {
   Thread.sleep(1000);
   } catch (InterruptedException e) {
  e.printStackTrace();
   }
   return Response.ok().build();
}

Trouble is that with this setup, I am only able to reach 10 requests per second. No more.I am testing this with SoapUI LoadTest - 100 threads, 1 ms delay between requests.

I bought a book called WildFly Administration Guide and tried some undertow settings:

• Stack size (500)
• Trying to set core-max-threads actually results in "failure-description" => "WFLYCTL0201: Unknown attribute 'task-core-threads'
• IO Threads (500)
  
  

Nothing helped.

Is this WildFly related problem, or something else?

Increasing of task-max-threads attribute may help. CLI command:

/subsystem=io/worker=default:write-attribute(name=task-max-threads,value=200)
