Resolving Dashboard refresh rate

Increase the update rate and tileCacheSize in config.xml

The dashboard is rendered in memory, then broken down into a number of images that are sent to the browser. If the update rate is set to be quick, then the image engine may not be able to keep up.

Try increasing the updateRate and tileCacheSize in the config.xml file with the following:

 <dashboardDefaults>
         <updateRate>10</updateRate>
         <dashboardRefreshRate>60</dashboardRefreshRate>
         <tileSize>
                    <width>200</width>
                    <height>200</height>
         </tileSize>
         <tileCacheSize>100</tileCacheSize>
         <tileCacheTime>30</tileCacheTime>
 </dashboardDefaults>

Update rate is in seconds, and the tilesize is in pixels
