Drawing Scaled Lines

Hi. I have an application in which I need to draw approximately 10,000 lines on each repaint. This paints very quickly when the scale of the image is 1.0 or less, but when I increase the scale to greater than 1.0, the slowdown several seconds. Below is a very crude example (that draws the lines in the same place, but still the slowdown is noticeable) that illustrates this point. Does anyone know why this happens and what can be done about it?



Thanks,
Jeff
