Hi,

Before relying on any third-party resources I'm experimenting with expanding 
Freemap (www.free-map.org.uk)'s coverage to the whole of England (will probably 
be Wales too next week) on my own server.

This is now live. It does mean that first time a given map tile is rendered 
(map tiles are GeoJSON-like and rendered by kothic-js, http://kothic.org) it 
will be _slow_ - perhaps 30+ seconds. I will try and optimise the backend sql 
queries by examining the native kothic python server-side code. 
However, the data is then cached meaning that next time you visit the area it 
will be much faster.

Freemap's web services (see 
http://www.free-map.org.uk/0.6/about.html#developer) do not seem to be impacted 
so strongly (in terms of a slowdown) as the renderer suggesting the rate 
determining step is somewhere in the rendering process. 

However I suspect both the renderer and web services will be very slow in 
London due to sheer volume of data. But TBH both the site and web services are 
more aimed at countryside use so I'm not too fussed by that.
