Is this really slow?

I''m working on a 3D terrain engine that renders a simple heightmap. I was playing around with OpenGL, trying to see what would be the best way of rendering the terrain so I wrote a little test program. However, in order to render a 10x10 tile map (with varying heights) I get a lousy 16 FPS! I''m running a P3 500 with an ATI 3D Rage Pro AGP 2x. I know that this isn''t the ideal 3D machine, but I know that Half-Life (and it''s various mods) runs nicely on this machine at 800x600 (probably low 20 FPS). What am I doing wrong? The tiles are rendered using GL_TRIANGLE_STRIP. The array of vertices is loaded into the vertex array. What''s wrong here? Here''s the link to my test program: http://chosendestiny.com/files/iso3d.exe
