[THIN] Re: How much Memory in servers

Don't use /3gb.
 
Don't use PAE.
 
Rewrite the app to use a decent db server backend and offload the data 
manipulation to it. Loading several gb's of data to memory on a citrix server 
and manipulating it there is stupid, lazy, and probably will perform worse than 
turning it into a client-server app.
 
(Have they even tried doing it the proper way?)
 
Sorry, but bad apps which hapless admins have to figure out how to run anger me 
greatly.

Have advanced and so far only have 3-4 users per box.  Is quite an intensive
app and is one of the few ways to run it remotely.  They basically load
several gig of data into memory and manipulate it when they run a report.
They want the quickest response time they can get.

You also need Advanced Server edition of 2000, it seems, for PAE.
Without that, you can't use more than 4Gb RAM
