SSAS - Sql Server Analysis Server Cube Performance question
I am working with SSAS and trying to figure out why our processing the cube on Production takes 3 times as long as the cube on Test.
Similarities and DIfferences
Data Warehouse - data in warehouse is identical.
Cube - almost identical. Test has a few extra columns exposed in the cube.
Database - both run on SQL Server 2008.
Operating System - Production - Datacenter Service Pack 1
Test = Windows Server 2003 R2, Service Pack 2
RAM - both have 8 GB
Processors - Production -3.20GHz
Test - 2.33GHz
Both have 2 processors
64-bit - both are 64-bit Operating Systems.
What else could be the difference?
Thanks,
Abbi

- SQL Server memory settings
- SSAS memory settings
- SQL Server index fragmentation
- SQL Server indexes - are the indexes identical in both DW's? Could affect if you have complex DSV in your cube.
- Server hardware, storage of SQL server databases?
You could run SQL Profiler on both of the machines when processing the cube, check the actual SQL queries run - and compare the performance on both servers.
