are you using a singleton lingo service object? if so, is it synchronized?
Sometimes, getting stacktrackes of the clients and servers will tell you
what your threads are waiting on most of the time.  I've got a feeling that
most threads will be blocked on some mutex in the business logic of your
service object.

First I had this scenario:

Machine A: Lingo Server, Lingo Client and ActiveMQ in three JVMS
=> throughput 200 Lingo request per second

Then I had this scenario:

Machine A: Lingo Server and ActiveMQ in two JVMS
Machine B: Lingo Client
=> throughput 4.5 Lingo request per second

So running an own broker in the server JVM to reduce the latency is a good
idea. But in both scenarios I had the Lingo server and ActiveMQ on the
same
machine and the decrease from 200 to 4 requests can not be a problem
between
server and ActiveMQ. Only the client moved to machine B. Do you agree?

Regards,

Bernhard
