You can go up to an NT machine and get right-now performance counters of just about every metric in the system. Every driver, every bit of kernel, every chunk of memory reads and moves etc.
Where is my RedHat equivalent to PerfMon?
If Linux isnt a fully instrumented OS from the ground up, then tuning it is always going to be a "finger in the wind" exercise at best.
Solaris has this stuff in... And guess what? It scales... There is no magic in this stuff. Until Linux gets to be instrumented from top to bottom, it will lag. Yes, I could go into the source and splatter in my own counters in all over the place: but they should be there, today.

Excuse me? "Several years"? Since when was NT *not* an SMP operating system? It was back in late 1991 when it first emerged into the light.
The inescpable reality -- NT has had nearly 8 years of SMP tuning, and the SMP mantra has been a religion for the NT group from the very beginning. That way they didnt end up with screwups like a single threaded IP stack

Its fairly simple, really.
