Hi Dennis,
that happens probably because the CPU is a multi-cores / multi-threads 
CPU with tens of cores / threads and the GDAL/OGR library or tool only 
uses one core / thread to execute such task.
I would suggest you to have a look at [1] and [2] for some performance 
improvement hints and to ask to the gdal-dev mailing list subscribers if 
you won't receive enough replies through this mailing list.

Best regards.
