I have a view that uses 11 outer joins and two inner joins to create the data. This results in over 8 million rows. When I do a count (*) on the table it takes about 5 minutes to run. I'm at a loss as to how to improve the performance of this table. Does anyone have any suggestions on where to begin? There appear to be indexes on all of the columns that are joining (though some are composit, not sure if that makes a difference...)
Any help appreciated.
