Of course, servers often serve up files to the user or run a couple of select applications (like SQL, Exchange, IIS, etc). So, there is no value really in trying to cache any applications since most start automatically. It's not often that an admin logs into the server and runs user based applications..like Microsoft Office, firefox, photoshop, etc.

Or within Windows 7 simply disable SuperFetch. And I seem to recall you said you were running on a Pentium 4 3.2Ghz system...that won't run 64-bit anyway.

Seems to me a winstat mem test showed that my RAM was moving approx 7GB/s. That crushes any hard drive or RAID config I have ever seen.

Also, that so called "used RAM" is available and can be as quickly overwritten as free RAM. I simply fail to see where the performance bottleneck occurs here and where all of this contention is coming from.

Actually it does, but it is set to background processes not your applications like IE or Firefox. A server OS is tailored to run background processes.

Fast forward...

One day, all RAM will have onboard batteries. Spazzie's grand-daughter will marry Bill Gates III and the world will live as one.

Prefetch or Superfetch? I see no superfetch service in Windows Server 2008 R2

Unlike Superfetch, prefetch does work, great explanation here:
JSI Tip 5826. What is the Windows XP Prefetch?

As a test, I turned prefetch off in XP and performance blows. So the next test is Windows 7 prefetch on, superfetch off for all round performance less all the disk/RAM contention between the users workload and the OS ..its akin to the user fighting with the OS for resources and that IMO is poor programming by Microsoft.

Neverending story about ram optimizers - most popular myth since Windows XP. I think that it would be nice to collect such myth in one post and made it sticky - it would save money and time for those who still believe in such applications.
