Yes, the site is an online-judge so it must remains open 24 hours. Because the users may submit a solution any time of the day, it must check por submitions pending to be evaluated periodically.

I used different styles like Double Buffering & Opaque.
The UI is windows.Forms, MVC means Model-View-Controller what is a dessign pattern.

I think the problem is the method that I use to manipulate the image. Each time a pixel is changed I invalidate the panel, so it has to totally repaint itself.
If I draw a single line of, in example 100 pixels, in a second, that means that for an 1024x768 image the panel (try to) paint 786432 pixels 100 times. What I think is much more that what my CPU can handle.
The problem is that I don't have idea of do this in other way...
