A throughput test is one thing. The second thing is to find out where the
performance problem is and the third one is to compare your results (e.g.
how the throughput is after you changes or what is the exact impact on
software reconfiguration, hardware changes or upgrades etc. etc.  If you
don?t want to spend a lot of time every time you are doing this, you should
use a reporting solution. On

sample performance reports.
