What you've described sounds very much like the computer running out of RAM and having to rely on disk paging. I imagine Adobe Professional has a pretty large footprint, and so do web browsers if you have open a lot of tabs. Combine that with a few Calibre processes and the OS and I wouldn't be surprised OS X starts hammering the disk.

It may be that Calibre has a memory leak where memory allocated when you import a new book into the database is not immediately released. So over time, as you add more and more books, the Calibre process consumes more and more memory until thinks reach a tipping point. Shutting down Calibre completely and restarting it would clear up that issue.
Of these, the last scenario is more likely than the other ones you've listed. I've used Acrobat Professional and Safari extensively and no problems.

I'll report back if there are additional developments.
