So you have the test webapp running on an otherwise (mostly) idle
system, and you are using JMeter from another machine (same network
segment) and still get terrible throughput? What does your JMeter test
look like?

What if you request a simple static resource -- something like
index.html? It's very possible that the web application itself is
terrible.
