Partitioning is good for managing very large tables because you can
rebuild 
individual partition indexes without touching the entire table.  This 
reduces rebuild time and intermediate space requirements.  Be aware that
the 
partitioning feature is available only in Enterprise and Developer
editions.

With a good indexing strategy, response time should ideally be
pro****tional 
to the amount of data retrieved (barring cached data) regardless of
whether 
or not partitioning is used.  Partitioning by date can facilitate certain 
processes, like incremental data loads and purge/archival as well as
certain 
types of queries.  However, with or without partitioning, indexing is the 
key from a a performance perspective.

Hope this helps.
