Performance is in the eyes of the user and "what they do."
Ya can't "benchmark" opinion.
What works for some does not work for others.
If they are skeptical, leave everything on the default and call it a day.
I have nothing to "prove," nor shall I attempt to convince anyone that "I am right."
I applaud skeptics, though, as I am a big skeptic and prove things (or disprove) to myself all the time and do not take anything that I read on the internet at face value.
I, however, do not leave things as Microsoft ships them (or anybody else for that matter) and "performance" of the OS is affected with what "I" do.
Ya can't "benchmark" that.
Adjusting services reduces the memory footprint of the OS and could plug some existing and future security holes.

Knocking out a few of those "extra" services could improve the performance of startup and shutdown with a system that is "underspec" with regards to Microsofts recommendations or even mine. Does that mean a $6,000 gaming PC would benefit? How about a system that is on 24/7 anyway?

What I offer is my experiences with tweaking an OS to squeak every bit of power out of my system that I can while costing nothing but time.

If anything, it makes Vista "snappier" to the user, but is that good?

Standard benchmarks, whether it be "hard drive" or "CPU" or "graphics card" or "pure data processing" like video encode/decoding do nothing but test those specific components or the entire system as a whole, not the "OS" itself. If the OS has a smaller memory footprint, you can load/do more things without worrying about the over use of swap space.
I am also a firm believer in "if ya do not use it or need it, why have it there" in the computer world. As a result, I have had great success in reducing the overhead of OS's and making a "noticeable" impact on performance "from my point of view." I am not talking .01% increase in frame rate in xyz game that only pure numbers would be able to show you, nor am I stating anything to the effect that "if you disable IPv6 support, your internet access will be faster," but why and the hell have it if I am not using it?

Really, though, what does a person have to lose but a bit of time and, maybe, just maybe, even gain some knowledge of their computer system in the process?

Now, if you are still with me, I do plan on banging around Vista in the coming months to see if I can get the OS down to a respectable "safe" value that "generally" people will consider useful, even the skeptics, and post memory footprints and comparing abc boot time to xyz with blah configuration, but that is after Vista SP2 is released and tested on my part. I am installing the beta on my VM systems "as I type." No, really... I am, but cannot do a lot until the final version.
