[OpenLayers-Users] speed up load tiles

[Ivan Grcic]

Hola Ivan,

few questions/tips...

1. How many layers do you have on map? There shouldnt be more then 2/3 tiled
layers on map. I got good results with  mixing tiled/untiled/vectors layers,
and changing these combination on different zoom levels

2. What kind of data do you have for layers? Do you have metatiling turned
on in tilecache? Putting big metatile values usually delays data response,
depending on data and server you are using.

Just open firebug in firefox and look into net panel, youll see urls from
