So basically I am pre-calculating a field for data mining purposes. Earlier it used to take 45 mins to complete but over the time the execution time has gone up to 4 hours.

There are two ways that SQL Server can use memory to make a query faster the second time you run it. Let’s talk about how the magic happens. 1) It takes CPU time to figure out how to run a query. SQL Server uses memory to cache execution plans to save time the next time you run the query.
