I have been rendering a scene, it takes only 5 seconds to render per image when the camera is set to HD 1080 image. But as soon as I dial HD 2160 in my camera, the render takes 5 minutes and half. I find it weird. Can someone point into right direction how make it to 20 seconds, which would be normal, according to my mathematical knowledge? (HD 2160 has 4 times more points, shouldn't render take only 4 times longer?)

SreckoMWell, ok, you are right.
Without looking at scene and some of the settings no one really can help …
So here is the scene. It is a box, mantra_ipr render (I just clicked render in the Render View)
the same setup with 1080 HD camera takes 6 seconds to render and the 2160 HD takes 0:07:09 which is 71.5 times longer.
I have an indie licence, so it can be due to that, or it is a bug, or I have no idea why would simply doubling resolution size result in 71.5 times longer rendering time.
I tried the same setup on the Mac machine, and surprisingly, everything works fine. So, now I am starting to think something is wrong with my windows machine. Should I RFE this?
