I remember running some very large reports over multiple years of inventory movement. Disk access on the server was totally saturated for a good 20-30 minutes.

Thinking about it now, it had to have read out the entire database multiple times.

Oh yeah, these reports weren't processed on the server, either. The network link on the terminal I used would be pegged at the max rate the server could read from the disk. I never really figured out what that's about.

I guess it's trying to stream large chunks of the DB to the terminal and running the query locally? No clue.

Some genius probably thought processing queries locally would be faster than on the database server. Fail.
