anyone still using analysis services 2000? each year i add a new partition to our cubes for the new year. we partition our data by year into separate sql tables and build AS partitions on these tables. i have tables & partitions for 1999 - 2012. all have approx 250,000 rows each and process in about 1-2 minutes. the new 2012 table has only 3300 at the moment, and it takes over 1 hour to process! i have checked the base tables for indexes (same as previous years) and the partition setup in AS but everything seems identical.

EDIT: i have the same problem on both our test and production servers.

any ideas on where to start?


p.s. before you tell me to migrate to a newer version - it's a legacy system that has been planned to be phased out but the phase out date keeps slipping. hopefully, it's only got 1-2 years left.

ok some success but not any understanding....

rather than linking the 2012 cube partition directly to the 2012 partition table, i link it to the main view (union of all the years' partition tables) and set a data slice to time = 2012. this processes in about 1 minute.

this is very strange because all of the other partitions are linked directly to the tables (NO data slice defined) with no performance problems. the 2012 partition table has all the same indexes as any other partition table.

if anything comes to mind please post, i'm curious what is behind this issue.
