What Aspects of Performance Are not Affected?the main impact of the 64-bit architecture is on availability of memory.Any aspect of performance that is purely CPU-bound, or exclusively dependent on the performance and responsiveness of the network or relational database, will not be affected.If a user wishes to look at a grid in Financial Management where the base data for the cells consists of 200,000 records in 10 subcubes

1. Data for the 10 subcubes is requested from the database (assuming the subcubes are not resident in memory). 2. Data is retrieved by the database and transmitted over the network to Financial Management. (Dependent on database and network;)

3. The records are indexed on-the-fly by Financial Management server, and stored in the subcube engine. (CPU-bound in the application server)4. Aggregation is performed in Financial Management server as needed and the resulting cells are transmitted to Financial Management Web layer. (CPU-bound in the application server)5. Financial Management client formats the cells as a grid and displays them to the user (Depends on the performance of the Web Server and browser )

if one or more of the subcubes need to be offloaded, the performance delay will put the 32-bit version at a disadvantage.The extra memory available to the 64-bit version will allow more users to access more data concurrently.Financial Management servers core operations, like aggregation, consolidation, etc., will be run as fast as the processor permits.

The 32-bit version was given a cache size of 2M or 4M records and the /3GB switch of Windows was used.

The 64-bit Financial Management was run with a cache size of 10M or 15M records, sizes that are impossible to achieve within the 32-bit address space.

A comparison of 32-bit and 64-bit versions with the same 4M record cache size demonstrates the two versions perform similarly, with the 64-bit version having a slight edge.
