The problem is with the Softing SDK, the test case creates 5.000 MIs
in one subscription, and the nested loop takes around 20 minutes
to process one publish response. Quadratic complexity, since both
the Publish response and the TempAnalogItems have 5.000 elements,
and, unfortunately the looked up item is always found at the end
of the TempAnalogItems array.

Proposed fix below: use ClientHandle as an index in the array,
to peel off one nested loop.
