Hi
On the server you need to push the server cache all the way up to its max, 40 megs will still have no affect on performance
The classic DB service is 32 bit so it cant handle more than 1 gig of ram (Which is why you should think about moving to SQL)
so change the cache on the server to 1024 000 the restart the server
The next bit is that the cache gets filled when the report or form or page runs, so run it a 3 times and then see what the run speed is on the 4th run
The object cache on your local machine will help but but you wont seen any dramatic improvements from that, i would say 50-100 megs is plenty
Cheers
