In all our services we observe that most of the CPU time is not consumed by the service logic itself but by CXF. I attach a picture (worth 1000 words) of a JProfiler snapshot. In the snapshot we see the PhaseInterceptorChain.doIntercept() taking 78.4% of the CPU which is fine as this includes the eventual service logic execution. What happens next is a bit strange, here is the ASCII art rendering: 78.4% PhaseInterceptorChain.doIntercept() 26.4% OutgoingChainInterceptor.handleMessage 20.0% ServiceInvokerInterceptor.handleMessage 16.9% ReadHeadersInterceptor.handleMessage The call to ServiceInvokerInterceptor.handleMessage() ends up calling the actual service logic which takes about 5% of the CPU time so, the extra 15% penalty seems to excessive, what's even more worrying are the other two handleMessage calls (OutgoingChainInterceptor and ReadHeadersInterceptor) that gobble up together more then 40% of the CPU. Note that we have no custom interceptors defined, our configuration looks like this: <import resource="classpath:META-INF/cxf/cxf.xml"/> <import resource="classpath:META-INF/cxf/cxf-servlet.xml"/> <import resource="classpath:META-INF/cxf/cxf-extension-soap.xml"/> <bean id="cxf" class="org.apache.cxf.bus.CXFBusImpl"> <jaxws:endpoint id="SomeServiceEndpoint" address="/SomeService" implementor="#someService" implementorClass="com.betfair.services.someservice.SomeServiceServiceImp l"> Is this behaviour expected in a properly configured system?
