Hej there,

At the moment I am working on my bachelor thesis using osm data to create cached-wms (wmsc).

I now have a running mapnik based tirex tile-server combined with a wms via mod_mapnik_wms. Next, I want to use the tilecache.org wmsc.

I have some questions and hope to find help along my path.

1. Are there any possibilties to check the performance of a wms/wmsc? I want to compare the server performance. I just need to see, if wmsc is faster than wms.

2. I thought wmsc has to be faster than wms - but nobody is using it, is there a reason?

3. I know the mod_mapnik_wms and the wmsc from tilecache.org - do u know more or better software, which does or doesn't work mapnik based? Is there an alternative to mapnik?

4. Is there a possibility to synchronize the database automatically, which i need to import from osm?

5. While importing via osm2pgsql the system used 4gb ram - how much would i need for the planet file?

I would appreciate any help.

Best regards,
Bernd
