[OSM-Devserver] NaviPOWM-Karten und Rechenzeiten

[Nic Roets]

For comparison:

Gosmore compiles the who planet in 7hours 16minutes using only 1 core.

Before I run gosmore I split the planet into 58 rectangles which will
probably be another 4 hours of osmosis. Splitting the planet into countries
will require a similar amount of computing power.

My suspicion is that single core will use less CPU seconds because of less
overhead e.g. synchronizing. But multicore may mean less cache misses as the
compression job "crowds out" other jobs. Difficult to analize and and test
will be somewhat subjective.
