Interesting article but the last couple of lines is the most interesting I thought.
The idea of getting better performance, just from slipping your database into RAM is intriguing, but I'm not sure that's the best way to improve performance. I'd argue training, time spent on resources like SQLServerCentral, and better code being written is the way to make your system run better.
The focus should be on writing better code but with the improvements in technology, this art is becoming somewhat of a lost cause. Flip side to this, should our focus be in writing good code or should it be to focus on solutions that solve real world problems?
Just a thought on a rainy Sunday afternoon. I truly believe the focus should be both...
