this looks lie reasonable approach however we will need to record not 
only improvement but also what was environment where tests were executed 
(what machine CPU/memory, network conection if relevant, OS version, JDK 
version)

we should gradually get to document how to run on a new machine all 
tests including setup of all required services (AXIS, tomcat, J2EE, ...).
