Select the Xconfig file in which you want to configure drawing settings and open the Exceed onDemand Xconfig dialog box. On the Performance page, select the appropriate drawing settings from the Drawing area. These settings let you manage drawing and backing store configuration to optimize performance.
Exact Zero-Width Lines Enables thin lines to be drawn and forces exact line drawing for zero-width lines. The X protocol states that zero-width (thin) lines are one-pixel-wide lines drawn using an unspecified, device-dependent algorithm. A line width of zero may differ from a line width of one in which pixels are drawn. This permits the use of many manufacturers' line-drawing hardware, which may run faster than the more precisely specified wide lines.
By default, Exceed onDemand lets the native operating system directly draw zero-width lines. This method is generally much faster than the exact-pixel algorithm used by X to draw lines of other widths.
Note: |
Certain video drivers ignore color information on some styles of zero-width line drawing. If lines appear in an incorrect color or do not appear at all, select this option. |
Draft Mode Improves performance with a slight and generally unnoticeable reduction in drawing accuracy.
Batch Requests Can help improve the performance of Exceed onDemand Server.
Save Unders If the Limit Window Exposures setting is disabled, you can use this setting to reduce network traffic and improve window refresh speed at the expense of window drawing speed and memory. When this option is enabled, Exceed onDemand saves background windows locally. When the option is disabled, the remote window manager refreshes background windows.
Limit Window Exposures Creates a backing store for all top-level windows, thereby reducing the number of expose events sent to the X application, which results in reduced bandwidth. The reduced redrawing reduces bandwidth usage and improves performance. This option is enabled by default. However, if your session is running over a fast connection, you have the option of disabling it, which may improve the performance of some applications.
