Well that is very frustrating. Because VEP7 uses 10-20% more cpu when the window is active for me here. I have reverted to VEP6 and run exact same project and VEP6 is using less CPU. Both VEP6 and VEP7 use a significant amount of additional CPU when the VEP window is open vs when its minimized. Personally I think that is concerni as well. Its even worse with a retina display. VEP7 is just a little worse then VEP6, those are MY results. I spent an entire afternoon running a precise test that would gather the results in a repeatable and exact way to be sure and I shared the test case with VSL. I can observe the additonial CPU usage as a percentage in the activity monitor and I have observe it in the loadavg value. they are correlated values.
If their answer is that their results are opposite of mine, I don't knwo what to say other then we have opposite results and that is frsutrating because my results are what they are.
I will not be able to run any more tests because the past few days I wasted of time with VEP7 and I am now reverted to VEP6 and will not try VEP7 again until at least a month goes by and poblems are more resolved.
