Speed Differences When Using Multi-port Extension

We have an assortment of different PNA's around here (a few N5230a's, n5230c's, and an n5245a) and found the trace load times/sweep times to be comparable among all three types.

However, we have an N5230c that's been deployed in a production environment with a U3042AE12 12-port extension attached. I'm seeing a massive time increase in this addition alone (~30-45 second increase in testing 8 parameters. So roughly a 3-4 second increase per sweep/setup).

Its worth noting that we're running a balanced setup and only sweeping across four ports at a time (1,2,3,4/5,6,7,8/etc.). The code that I've developed for both of these units is virtually identical save for the use of only 1 balanced setup versus 4.

Can I safely attribute the time increase to the extension?
If this isn't the case, is it possible we're seeing a huge time difference in the two n5230c units I have to test on?

Thanks in advance.
