Do you deploy both the uima-as client and a service in the same process?
How do you get your timing? There is a CAS serialization/deserialization
penalty and latency in a broker but should not be huge. The design goal is
to support scaleout of analytics across multiple processes on multiple
machines. For maximum performance we recommend sending a CAS with a
reference to data to be analyzed instead of sending data in the CAS.

How big is the CAS you are sending from the client? If you are using a
default FC, there should be no significant delay there.
