Is there a way to configure spare / minimum threads to Wildfly and undertow thread pools ?
I haven't looked into the details but perhaps you might have to configure the IO subsystem's io-threads attribute wildfly/build/src/main/resources/docs/schema/wildfly-io_1_1.xsd at 8.1.0.Final · wildfly/wildfly · GitHub. I don't know if that attribute is supposed to represent the "min threads" that you seem to be after. Give it a try and see if it makes a difference.
