I am trying to generate OD Cost Matrix in a model and generating the matrix for 5,000 origins and destinations takes about 15 minutes, but the next step is to Save to Layer File in order to persist the matrix, and is taking hours. The first two attempts I thought something had gone wrong and killed the machine and rebuilt the model after a couple of hours, the most recent attempt I have left it running and it is going on 9 hours for the Save to Layer File step.

How can saving the file take so much longer than generating the matrix?

Is there a better way to persist an OD Cost Matrix? Save to Layer was the only method I could find.
