The difference between them are how data is populated for each of these operators.In general Spool temporary tables are referenced as worktables in I/O stats. Why does the Table Spool/Eager Spool take up 60% of the time it takes to generate the SELECT INTO statement ? It was generating fine in about 3 seconds and now it takes about 90 seconds to generate. The only thing I changed was a VIEW but the view speed difference is only about 1-2 seconds. Old server was a physical server, the new server is a VM (Hyper-V). After the upgrade the execution plan looked different from the old one and it seems to use Index Spool (Eager Spool) instead of using index.

Which means that execution time went from 3 seconds on the old server to 1 minute 50 seconds on the new server.

So in this case, the Eager Spool forces the read of the @oriopr table to be completed before any new rows are inserted into the @oriopr table. Eager spools are also inferior to lazy spools. I don't have any solid tips for making your eagers turn into lazies, but the concept of working with only a small amount of data at once and putting it all the way through the pipeline suggests an alternate method: Batch your work into smaller pieces of 1000 or 10000 rows at once.

The Index spool/eager spool reformats the data from input to a temporary index which is then used for seeking based on a seek predicate.

There are two types of spool operations, eager spool and lazy spool. A spool is basically a temporary table created within the execution of the query that is used when it’s likely that data will be needed again, and again during the execution of the query. Index spool / eager spool costing 70% of query. Hi, After installing SP3 I have a query that is taking about 10 times longer to execute. When I turn on the query analyzer exection plan I see that 70% of the cost is in doing an Index spool / eager spool step after a table scan.

In the case of a lazy spool (LS), the spool only stores the individual rows that are requested by its parent, not all of them. Now when I look at the execution plan it shows that 44% of the query's cost is the Table Spool (Eager Spool) of my SELECT (blah) INTO #tempTable query.
