[mkgmap-dev] Why does splitter limit the number of threads?

From GerdP gpetermann_muenchen at hotmail.com on Fri Nov 25 12:57:40 GMT 2011

Hello list,

the current implementation limits the number of threads to the number of
available cores.
I changed the code to allow +2 threads. This results in a much better
throughput on my dual core machine 
(e.g. germany.osm.pbf is 100 seconds or 17% faster) with r190 + patchv7.
What could be the reason for this limit?
