That’s not 100% correct Nick. Using Enterprise Edition you can enable /PAE in 
the boot.ini so that the “System” will see all the RAM. No apps will be able to 
address the memory above 4GB, but the System will use it as virtual memory. 
There have been many studies done that say that this will provide a 
considerable performance boost. I would still start with a 4GB page file, but 
you may be able to decrease this or remove it altogether. However, if you still 
want to enable kernel memory dumps, leave an 850MB page file on the System 
drive. You would never do a full memory dump!

 

Cheers,

Jeremy.

The x86 OS will only see 3gb Ram in any case so you don't need to worry too 
much.

        Hi
        
        Im building new Windows 2003 Enterprise servers with XenApp 4.5 (32 
bit).  Servers have 16Gb RAM.  Hardware was originally sized for x64 but we 
must go with x86.  How big should the swap file be if server has 16Gb RAM?  If 
I follow the RAM X 1.5 rule I will end up with a 24GB swap which seems like 
overkill.  I have the disk space but was wondering what the best practice is or 
if there are dissadvantages in using a large swapfile.
        
        Thanks
        Angela
