A DESCRIPTION OF THE PROBLEM :
The built-in JAX WS server implementation works 100 times slower on linux machines then on Mac OS X or Windows. JMH test is published here: https://github.com/Andremoniy/linuxjvmjaxwstest

Basically it does the following:
1) starts a JAX WS with one SOAP method:
endpoint = Endpoint.publish("http://localhost:8888/", new FooServiceImpl());
2) performs client requests to this method:
String result = state.client.foo(state.foo);

On Mac OS X with 2 Cores Intel Core i7 it gives:

# JMH version: 1.19
# VM version: JDK 1.8.0_151, VM 25.151-b12
# VM invoker: /Library/Java/JavaVirtualMachines/jdk1.8.0_151.jdk/Contents/Home/jre/bin/java
...
Result "test.openjdk.MyBenchmark.testMethod":
  3077.813 ±(99.9%) 51.818 ops/s [Average]
  (min, avg, max) = (1718.347, 3077.813, 3315.271), stdev = 219.400

The same machine, docker without CPU limitations:

# JMH version: 1.19
# VM version: JDK 1.8.0_151, VM 25.151-b12
# VM invoker: /usr/java/jdk1.8.0_151/jre/bin/java

The situation changes if JAX WS server is started with Jetty (there is no performance issues):
    ContextHandlerCollection contextHandlerCollection = new ContextHandlerCollection();
    server.setHandler(contextHandlerCollection);

    JettyHttpServerProvider.setServer(server);
    HttpContext context = new JettyHttpServerProvider().createHttpServer(new InetSocketAddress(8888), 5).createContext("/");

    Endpoint endpoint = Endpoint.create(new MyBenchmark.FooServiceImpl());
    endpoint.publish(context);

    server.start();

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
On linux machine (for instance, docker pull openjdk:8u151)

git init
git clone https://github.com/Andremoniy/openjdkjaxwstest
mvn package
cd target
java -jar benchmark.jar

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
The performance should be the about 3000-5000 ops/s.
ACTUAL -
The performance is about 20 ops/s.

REPRODUCIBILITY :
This bug can be reproduced always.

CUSTOMER SUBMITTED WORKAROUND :
Use Jetty server for publishing WS.
