Previously tracked at: https://bugs.openjdk.java.net/browse/JDK-8193236
FULL PRODUCT VERSION :
openjdk version "1.8.0_151"
OpenJDK Runtime Environment (build 1.8.0_151-8u151-b12-1~deb9u1-b12)
OpenJDK 64-Bit Server VM (build 25.151-b12, mixed mode)
ADDITIONAL OS VERSION INFORMATION :
Linux c0ab5270bb70 4.9.49-moby #1 SMP Wed Sep 27 23:17:17 UTC 2017 x86_64 GNU/Linux
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
CI (99.9%): [3025.995, 3129.630] (assumes normal distribution)
The situation changes if JAX WS server is started with Jetty (there is no performance issues):
ContextHandlerCollection contextHandlerCollection = new ContextHandlerCollection();
server.setHandler(contextHandlerCollection);

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.
