 thousands of polygons, not just two. In Windows this is being done
 within milliseconds and normally in Linux, too. Only, if in Linux some
 GraphicsPath are extremely zoomed instead of milliseconds the Linux
 version needs several minutes (!) to render everything.
 BTW: a call to Graphics.Clip (Region) seems to improve performance a bit. 
+------- Additional Comments From gonzalo at ximian.com  2006-05-17 13:12 -------
+This is what I get on linux with current svn and your 50-lines test:
+gonzalo at lalo:/tmp/gdiplus $ time -p mono zoom.exe
+real 0.14
+user 0.09
+sys 0.02
+On windows, with MS runtime (different computer, btw):
+$ time -p ./zoom.exe
+real 0.15
+user 0.03
+sys 0.00
+So this is fixed now.
