[OpenLayers-Users] please some hints for very low bandwith

[Pere Roca Ristol]

  hi all,
  I need some hints to take into account when having a veeery low bandwith.
  I have already set up background layers as PNG8 (jpeg does't accept
transparency) and vectorial as jpeg.

  I wonder if in these situations tiling is better than normal WMS (?)
  Currently I  have an untiled layer. The "map" is 800x350. I wonder why the
generated untiled image
 is 1200x525; I know Openlayers creates a buffer on tiles, but it also is
applied on untiled layers?
	     
   If tiling is better than Untiled (taking into account low bandwith as
critical factor) I  want to keep the number of tiles to minimum. So, I don't
want any buffer. I set layer like this:
	     
	     var admin = new OpenLayers.Layer.WMS( "my WMS",
                "http://mywms/wms",
                {layers: 'mylayer',transparent:"true",styles:'mystyle'"}
				,{'displayInLayerSwitcher':false,tileSize: new OpenLayers.Size(400,175),
buffer: 0});
	     
    but instead of getting 4 tiles I continue getting 6 (2 of them covering
out of BBOX); have also tried buffer:1 without success
 
    thanks in advance,
    Pere
