    I've noticed that the first exec of an INSERT prepared statement
    takes ~5 time longer (I'm using libpq in C and wrapping the calls to
    time them) then subsequent exec's is this the expected behavior and
    if so is there any thing I can do to mitigate this affect?

For example (in my environment) I'm seeing the prepare take ~10ms, the 
first exec take ~30 ms and subsequent exec's take ~4 ms.


I don't have an answer. I believe though that to help those that might 
it would be helpful to show the actual code.
