Insufficient Memory May Be Limiting Performance

Dear Forum 7 Experts,

I have an Excel application that uses 3 GB of memory when it is idle. When is is running the app will use up to 10 GB of memory. My memory configurations are as follows:

Physical Memory

Installed

32 GB

Excel App

10 GB

Other Processes

3GB

Cached

2 GB

Free Memory

17 GB

Kernel Memory

Paged

377 MB

Non Paged

123 MB

The Excel application seems to run okay for the first hour. But, since the app uses more memory, as time progresses, it eventually slows down to a snails pace. The program is written impeccably to conserve memory but its associated and growing tables of data would seem to be too much for the system to handle.
Since my workstation can handle up to, I think, about 600 GB of memory, I am wondering if i need to purchase more memory or whether there is something else i can try to relieve the performance bottleneck.

Any help would be appreciated.

I believe a fellow by the name of Sir George solved this problem for me. After converting from a lower version of windows 7 to Windows 7 Ultimate, the problem went away because the operating system can now fully utilize the memory that I have installed. Nice going sir.
