Hi Henry,

I have just read your comments on RAID0 and I have indeed experienced exactly the same with similiar conclusions.
I am now tuning FSX (RAID0) on a very large VISTA ASUS MAXMUS EXTREME QUAD CORE system and I am investigating how to optimise Memory Management.
The article written by Jeff Atwood in
http://www.codinghorror.com/blog/archives/000688.html
and the subsequent forum discussion is very informative and well worth reading and investigating.
I have improved my frame rates significantly by understanding what is happening but also expensively by using 4GB of DDR3 1800 overclocked.
The reality is that you are wasting your time and money in a VISTA 32 Bit system by having anything over 3.5GB (approx.) of memory. This is important for people contemplating purchasing more than 4GB of expensive memory - not a good investment!
It is also worth remarking also that "the jury is out" on the advantages of dual channel versus single channel memory in terms of its contribution to performance. My experiments to date demonstrate no observable improvement!
The interesting part of all this is the significant positive difference Super Fetch makes to VISTA performance and also the cache management strategy.
Have you done any experiments in this area as I would be delighted to share
my experiences.
Bill.
