Rendering mesh polygons in OpenGL - very slow

I recently switched from intermediate mode and have a new rendering process. There must be something I am not understanding. I think it has something to do with the indices.

Here is my diagram: Region->Mesh->Polygon Array->3 vertex indices which references the master list of vertices.

Here my render code:

// Render the mesh
void WLD::render(GLuint* textures, long curRegion, CFrustum cfrustum)
{

    int num = 0;

    // Set up rendering states
    glEnableClientState(GL_VERTEX_ARRAY);
    glEnableClientState(GL_TEXTURE_COORD_ARRAY);

    // Set up my indices
    GLuint indices[3];

    // Cycle through the PVS
    while(num < regions[curRegion].visibility.size())
    {
        int i = regions[curRegion].visibility[num];

        // Make sure the region is not "dead"
        if(!regions[i].dead && regions[i].meshptr != NULL)
        {
            // Check to see if the mesh is in the frustum
            if(cfrustum.BoxInFrustum(regions[i].meshptr->min[0], regions[i].meshptr->min[2], regions[i].meshptr->min[1], regions[i].meshptr->max[0], regions[i].meshptr->max[2], regions[i].meshptr->max[1]))
            {
                // Cycle through every polygon in the mesh and render it
                for(int j = 0; j < regions[i].meshptr->polygonCount; j++)
                {   
                    // Assign the index for the polygon to the index in the huge vertex array
                    // This I think, is redundant
                    indices[0] = regions[i].meshptr->poly[j].vertIndex[0];
                    indices[1] = regions[i].meshptr->poly[j].vertIndex[1];
                    indices[2] = regions[i].meshptr->poly[j].vertIndex[2];

                    // Enable texturing开发者_如何学Go and bind the appropriate texture
                    glEnable(GL_TEXTURE_2D);
                    glBindTexture(GL_TEXTURE_2D, textures[regions[i].meshptr->poly[j].tex]);

                    glVertexPointer(3, GL_FLOAT, sizeof(Vertex), &vertices[0].x);

                    glTexCoordPointer(2, GL_FLOAT, sizeof(Vertex), &vertices[0].u);

                    // Draw
                    glDrawElements(GL_TRIANGLES, 3, GL_UNSIGNED_INT, indices);
                }
            }
        }
    num++;
    }

    // End of rendering - disable states
    glDisableClientState(GL_VERTEX_ARRAY);
    glDisableClientState(GL_TEXTURE_COORD_ARRAY);
}

Sorry if I left anything out. And I really appreciate feedback and help with this. I would even consider paying someone who is good with OpenGL and optimization to help me with this.

There is no point in using array rendering if you're only rendering 3 vertices at a time. The idea is to send thousands through with a single call. That is, you render a single "Polygon Array" or "Mesh" with one call.
