[OpenLayers-Users] Optimization of raster WMS layers

[jdmorgan]

Hello,

I am following up on this posting as i am still having this issue.  I 
was it is possible to speed up openlayers without using a tileCache.My 
test page is only working with three layers and yet it is fairly slow 
compared to loading the same data through a Flex viewer (that also 
doesn't use a cache).I am sure it is just a matter of a config parameter 
I am not setting correction. Here is my js when loading the layer:


     var streetMap = new OpenLayers.Layer.ArcGIS93Rest(
         'ESRI Streets',
'http://server.arcgisonline.com/ArcGIS/rest/services/World_Street_Map/MapServer/export?f=image', 

         {layers: 'show:0'},
         {}
     );

     var stateMap = new OpenLayers.Layer.WMS(
         'States',
         'http://linuxserver/~user/html/vlayers',
         {layers: 'states', transparent: true},
         {
             isBaseLayer: false,
             transitionEffect: 'resize'
         }
     );

     var bigRasterLayer = new OpenLayers.Layer.WMS(
         'EFETAC-NASA_AllYrBaseline_current',
         'http://linuxserver/~user/fswms/html/ews',
         {layers: 'CONUSRasterData', transparent: true},
         {
             isBaseLayer: false,
             transitionEffect: 'resize',
             buffer: 0
         }
     );

     mainMap.addLayers([streetMap, stateMap, bigRasterLayer]);
     mainMap.setCenter(new OpenLayers.LonLat(-98.0859375, 
39.095962936305476), 5);
