2 Answers
- Use partition switch to move ‘in’ the data. This is, by far, the best solution.
- Make sure the INSERT is minimally logged. Read Operations That Can Be Minimally Logged and Prerequisites for Minimal Logging.
- Make sure your IO subsystem is capable of driving a fast load. Read Introducing SSDs.
Why insert is slow in SQL Server?
I know that an INSERT on a SQL table can be slow for any number of reasons: Existence of INSERT TRIGGERs on the table. Lots of enforced constraints that have to be checked (usually foreign keys) Page splits in the clustered index when a row is inserted in the middle of the table.

How to improve SQL Server table insert performance?
The execution speed of this query is too slow to be useful. Because the query takes too long to process, I tried out following solutions: Split the 20 joins into 4 joins on 5 tables. The query performance remains low however. Put indexes on the foreign key columns.
Is it possible to speed up SQL INSERT?
If so then you should also consdier the locking implications. Note that SQL Server can suggest indexes for a given query either by executing the query in SQL Server Management Studio or via the Database Engine Tuning Advisor. You should do this to make sure you haven’t removed an index which SQL Server was using to speed up the INSERT.
How to speed up the performance of insert?
Set the fill factor to 0 or 100 (they are equivalent) so that no space in the table is left empty, reducing the number of pages that the data is spread across. Change the recovery model of the database to Simple, reducing the overhead for the transaction log.
