First, if the broker is using persistence, try turning off persistence
(persistent=false in the broker tag).  If that eliminates the delay, it's
related to storage.  If not, storage is not involved.

Using a java profiler, such as Yourkit, also comes to mind.

Is there any benchmark against which the 120ms is compared to determine it
is a "long time"?  Also, are the producer and consumer both on the same
server as ActiveMQ to rule out network latency?  And, is this delay seen
consistently across a large number of produced and consumed messages?

BTW - another thing to check - make sure the producer and consumer are not
closing and recreating connections; ActiveMQ (like all JMS) connections are
intended to be long lived, processing large numbers of messages in a single
connection lifetime.
