My code is gonna below:

            toolbar.SetBuddyControl(map_main.Object);

            rgb.Red = 255;
            rgb.Green = 0;
            rgb.Blue = 0;
            rgb.Transparency = 255;

            ISimpleLineSymbol outLine = new SimpleLineSymbolClass();   //The outline.
            outLine.Color = rgb;
            outLine.Width = 3;  //The width of the outline.

            rgb = new RgbColorClass();  //The fill color.
            rgb.Red = 255;
            rgb.Green = 0;
            rgb.Blue = 0;
            rgb.Transparency = 0;

            mapContainer.AddElement((IElement)shape, 0);
            IActiveView view = mapContainer as IActiveView;
            view.PartialRefresh(esriViewDrawPhase.esriViewGraphics, null, null);
        }

It seems that I refresh so much or someting else,and I always want to search for improving the performance.
Could you launch someting? Thanks very much.
