There were a couple concerns we had.
The first one, which it seems like everyone is thinking about, is the concern that the pages could hurt our overall ranking. I don't know if they do or not. I would love to find that out.
The second concern is load time. That particular website is a Drupal site. It has always been slow compared to our WP sites. Drupal calls MySQL more for each page. The more records the slower the load time.
Now, perhaps a site with only 10K records will load quicker than one with 30K. Maybe a third quicker? I have found that the number of records doesn't matter much on WP.
