Answer 1

If you are looking at the profiler and there is no difference between the executions then the difference must be with the client systems.

4 mins does seem like to long just to prepare a statement to send so the 12 min wait must cause some other effect -- no idea what it is.

Does the Java case include transmission of the results to the Java server (network overhead) plus some Java processing? A 12 minute query might produce quite a large amount of data.
