Is there any reason to believe that putting two oscilloscope-type windows in one plot (with the new 'multiple axis rects in one plot' feature) would provide better better "scan-rate" performance that having each in its own separate plot? I ask because the ->replot() command takes up the most time and if they were combined it would only need to be called once.
Otherwise, is there any way to make the replot() command take up less time besides what is list "Performance Tweaks"?
