I am developing medical GUI application in which i am ploting real time graph with 5 milisecond refresh rate using Crank storyboard.
Graph ploting is taking upto 80 milisecond to draw the graph whereas the redraw time is only 5 miliseconds, and it is also taking 85% of CPU consumption.
when i draw a graph with draw time 140 miliseconds, CPU utilization is decreased to 35-45%.
kindly help me out and give some solution to optimize the redraw time upto 20 miliseconds.
