I did a load test of my Rails application yesterday, running 8 dynos with 3 concurrent Unicorn processes on each. This is the New Relic output:

As you can see, my Rails stack itself has a pretty good response time (DB, Web, etc), but the queue time is super terrible.

What can I do about this? Is this inherent in Heroku performance, or does it just mean I need to add more dynos?

Any advice appreciated.
