Use Polyxxxx set of functions. Some of the functions that I know are listed below

  1. PolyPolyline
  2. PolyTextOut
  3. PolylineTo
  4. PolyDraw
  5. PolyBezier
  6. PolyBezierTo

From MSDN:

These functions exploit the fact that many drawing calls use identical attributes, and so multiple items can be drawn in a single call once the brushes, pens, colors, and fonts have been selected. For example, the console window uses PolyTextOut. This change significantly reduces scrolling time in a console window.
