The official recommendations are just the ones filemaker lists on their tech specs for the product line:
In terms of localized performance, it's more of an IT issue in addressing the user's needs.
IE if the user needs to run 10 programs in tandem with filemaker, they'll need more resources on their machine than someone who only runs 3 programs.
As for the "memory" tab under preferences, your needs can vary wildly as well depending on what you're doing in filemaker. 64mb of file cache is enough for a lot of people. If you're doing intensive number crunching it might require a boost to 128 or 256.
Remember that increasing this can have consequences elsewhere. And turning filemaker into a resource hog won't necessarily win over your user's hearts if their other programs start crashing.
Thanks Mike. I didn't think to ask how many other programs they had running. I think my script is a little slow OnOpen which I need to clean up but otherwise I do not think that FM is slow.
Yeah, it might be good to optimize your loading scripts if that is where the performance issues are noticed the most. If there are other performance issues throughout the solution you might want to consider using an optimization utility like 24U's FMBench http://fmbench.com
