[undertow-dev] Advice on measuring filter performance overhead without networking activity

Hi folks! I would really appreciate a piece of advice on how to do something. I'm working to measure the performance overhead adding the opentracing filter to a webapp (using java-web-servlet-filter library from https://github.com/opentracing-contrib/java-web-servlet-filter). Until now, I have a test, using JMH to start to deploy and simple servlet application and start the undertow server and test it using an http client. But I want to measure in the server side without considering the networking activity. How can I do that? My test, for now, is: https://github.com/gsoria/jmh-examples/blob/master/jmh-examples-java-serv... Thanks in advance -- Gabriela Soria
