There is a Webinar on our SimCompanion site that addresses performance issues. This one is a bit older, but is great if you are running an older version of Nastran (prior to v2017 or so):

Here is a Webinar that touches on the BPOOL capability in the newer releases:

Checking the f04 for SPILL is a good idea... here is an article for that:

And lastly, looking at the High Performance Computing User Guide is a good idea... look at the sections related to running SOL108 or SOL111 (Frequency Response):
