VNCplay records a user's interactive session with a system and replays it multiple times under different system configurations; interactive response time is evaluated by comparing the times at which similar screen updates occur in each of the replayed sessions. Using VNCplay we studied the effect of processor speed and disk load on interactive performance of Microsoft Windows and Linux. These experiments show that the same user session can have widely varying interactive response times in different environments while maintaining the same total running time, illustrating that response time is a better measure of interactive performance than throughput. The experimental results make a case for a response time measurement tool like VNCplay. I am thinking that this would be an ideal tool to actually quantify QEMU performance, instead of all of us saying "Oh, this feels a lot faster".
