[OSM-talk] tile server

[SteveC]

the slippy map has been failing since nicks code change because it's
been attempting to draw streets on every tile. I've explicitly set the
layers in the javascript. I've moved tile caching to the new tile
machine and the old tile now just draws the streets.

Tile drawing now appears to be limited by cpu speed rather than memory,
as it's no longer trying to load the entire planet... it has a lot more
free memory and isnt swapping yet.

Central london, my usual test case, is working most of the time now.
It's not perfect - there are old cached tiles in there too.

There is still much to be done, the tiles should be cached for longer
and there is a new tile generating machine pending from nick hill which
depends on some funding. Some apache tuning can be done now the memory
footprint has changed.

But it's enough for one day.

have fun,
