[OpenLayers-Users] How to display a lot of tiles fast?

[Steve Way]

For a start, I would not have them split into the OS grid structure by folder - I would place all geotiffs and world files in one folder(They should all have different file names and if not, run a process which changes the filename to the corresponding folder, then move them e.g. if it is 123456.TIF then rename TQ123456.TIF and TQ123456.TFW) and serve them through geoserver and one image mosaic layer.

That way, you will be able to seed geowebcache properly, and the openalyers performance will be increased- you can setup geowebache to serve either TMS or WMTS.

Hi,

I'm trying to use geowebcache, but get an error when I try to seed any tiles. I'm also setting the minimum scale but even at levels where it should only be pulling back 1 -9 tiles, it is still very slow, I'm assuming that it is having to do a lot of looping through the layers (43) to see if the extent is covered. It worked OK as a group layer when I had 2-3 mosaicLayers added, but has locked up with the 43 layers present.

What is the TMS layer supposed to do? From you sample code it looks more like a layer suitable for prebuilt tilecaches. The folders I have contain geoTiffs with wtf files, so I'm not sure I can load them in like you suggest.

Any other ideas?

Rob
