[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 --shared-memory=yes -t 2 -p 5000" 3 cpu-cores are raise up to 30-50% usage and i only get ~333 routes per second. so i also try run 2 instances with one core: "osrm-route --shared-memory=yes -t 1 -p 5000" "osrm-route --shared-memory=yes -t 1 -p 5001" and use ngnix as load-balancer .. it dosn't make a difference to one instance with 2 or more threads what is wrong? with "-t 2" or 2 instances i expect that 2 cpu-cores are at 100% and i get more routes per second as with "-t 1". ___ OSRM-talk mailing list OSRM-talk@openstreetmap.org https://lists.openstreetmap.org/listinfo/osrm-talk
