While I'm not a user, one thing has occurred to me.

Back in the day, when everything ran on one CPU, it didn't matter which 
process was running, the CPU could do only one at a time.

Now today, with lots of CPUs (cores), multiple things can occur 
simultaneously, and if every user is waiting on the Oracle engine to 
service their needs, it probably is harder to scale that up, than to 
scale up with the Rdb concept of running in the user process.

And maybe Dave doesn't know what he's talking about.  (Same old 
territory for me.)
