16. • What impact does this decision have on the performance?
• Are all performance requirements fulfilled?
• Are all performance requirements fulfilled for all relevant configurations?
• Having an incomplete configuration, which features yield the best
performance?
• Oh this is interesting, can we have a thorough analysis?
