I was fighting with this few days ago. It seems, that tiles are
generated not for the extents of the base layer being tiled, but for the
extents of the largest layer from the map. What I had was county map,
not very detailed, with one municipality with full detail. I wanted to
create tiles for this very detailed part (approx. 1/20 in both
dimensions). And the surprising part was that "empty" tiles, which are
400 times more than the "useful" ones, were not generated faster. I
guess Daniel is facing the same problem.

It’s also a bit suspicious that it’s generating 400M tiles – that’s
something like 20K tiles in each dimension. I’m not sure what extent
your map covers, but that seems like it would be too detailed of a
scale for anything but whole-world maps.

Yes, I think you are just hitting the point! J
maybe I need to set the scales to generalize some layers and try again.
cheers,

just raster data? is your data too detailed, ie you
can generalise you data to match the scales your
rendering...
you should be looking at using at least a dual quad core
server for that size of a map
how long does it take to render a map in the browser?

Hi all,
Anyone have generated tiles using MgCooker? How long did you take to
complete it?
Here is mine:
It has been running for 12hrs, and generated 10,044 of 458,315,636
Remaining tile : 1218080:51:27 !
That’s horrible, will it take days, several weeks, or even months? ?
Am I missing something to improve performance?
===================
Layers: 28 layers,
Scales: 3 (actually, I was planning to set it to 7, but it costs too
much timeL)
Thread: 10
Server: Intel Pentium D CPU 3.0GHz *2
RAM 2G
Windows 7 Enterprise
MapGuide OpenSource 2.1 with Autodesk Raster FDO
Maestro 2.0
