The baseline CPU load of CVI should be about 4-5%. If you have ui editor windows open, and especially if in those windows there are timer controls, or there have been timer controls in the past, then that number can increase, depending on how short the timer intervals are.
I'm a bit skeptic that CVI's CPU load -- especially the baseline load -- would have much of an effect on the performance of other applications. CVI adjusts its sleep policy based on the current system activity, in such a way as to reduce its load when outside activity increases.
