Our indexing process is to adding a bundle of solr documents(for example 5000) to solr each time, and we observed that before commiting(which might be io bounded) it uses less than half the CPU capacity constantly, which sounds strange to us why it doesn't use full cpu power. As for RAM, I don't know how much it will affect CPU utilization, we have assigned 14gb to the solr tomcat server on a 32 gb linux machine.
