- True, but what about a well-designed machine with properly balanced
- subsystems AND a screamingly fast CPU? When I got my first 386-25DX
- it was SCREAMINGLY fast. Several people who bought them all agreed
- that things were practically instantaneous and that there was no need
- for anything faster. I still have that machine, and it feels
- SLUGGISH. Of course, my main machine is now a 486-50DX with three
- times the memory, and (for now) IT feels quite fast. I do not doubt
- that a few years down the road it, too, is going to start to feel
- sluggish. Then I'll be in the market for a 686-66DX or a SPARC10.
-
- Let's face it. What feels 'fast' is based upon expectations, and as
- new software is developed, it tends to be larger, more capable, AND
- SLOWER, requiring greater resources to get 'acceptable' performance.
