Query very slow via JDBC compared to Query Analyzer

I am trying out the JDBC driver SP3 for data access in a Java application,
and I find that some of the queries I had tested in Query Analyzer are
returning very slowly in my Java application. The queries not extremely
complex (just a couple joins), and they return small datasets (on the order
of 2-20 rows with 2 columns each).
In one example, I am waiting about 20 seconds for a query to return in my
Java application where it took less than one second in Query Analyzer.
I'm not really sure where to look to address these performance issues. Is
there something obvious I might have wrong on my connection string? I connect
to SQL Server over 100Mb Ethernet.
I'd appreciate any help!
Thanks
OK, it seems I did not choose very good search parameters when I looked for
answers previously... turns out the SendStringParametersAsUnicode as the
culprit. Sorry =) But thanks to those who posted previously.
