And yes, for large tables, they can increase performance.

Straight out of the Books Online:

CREATE PARTITION FUNCTION myRangePF1 (int)

AS RANGE LEFT FOR VALUES (1, 100, 1000) ;

GO

CREATE PARTITION SCHEME myRangePS1

AS PARTITION myRangePF1

TO (test1fg, test2fg, test3fg, test4fg) ;

GO

CREATE TABLE PartitionTable (col1 int, col2 char(10))

ON myRangePS1 (col1) ;

GO

Tip :-

Once you implement partitioned table and are going to implement Sliding window.

Make sure that you split and merge partitions which are empty.

Splitting or merging a partition(s) containing millions of rows in it will be

catastrophic for your IO.
