Hi,

I have a SP in my app that creates a cursor with between 20,000 and 100,000 rows. It is used in a matching routine to match records from one table to records in another table (it is a financial transaction reconciliation application).

At any rate, this SP has always finished processing within 1 - 4 minutes - which is acceptable when we're processing over 100,000 records.

On one of my P.C.'s - which had been executing this query between 1-4 minutes up to a couple of days ago - now the query is taking 10 minutes to process just 20,000 records.

(Note: I did some testing and it confirmed that it was taking this long to loop through the cursor - in other words - it wasn't something else in the SP causing the bottleneck)

Is there something that can explain why a query that has been consistently running at acceptable speeds for a number of months - all of a sudden is running like a dog? This has me baffled.


Thanks, Al
