[OSRM-talk] osrm performance with multiple threads is confusing me

I'm a little bit confused. i have load the map in memory with osrm-datastore und run one instance with "osrm-route --shared-memory=yes -t 1 -p 5000" with only one thread, one cpu-core raise up tzo 90% and i get ~500 routes per second if i set thread count to more then 2 or more "osrm-route
