Have you tried to start two independent logstash instance at once? Maybe you are limited by logstash output plugin not by elasticsearch itself?

For data rate 17k/sec is about 1 468 800 000 documents a day it a lot but can be handled by one es instace. But if you are planning to keep this data for a long period one instance is not sufficient.
