Hi
I converted a Non Partitioned table to a Partitioned table (both same index). in the partitioned table i added new Stat Column(Partition).
 
I found that the new table (PPi) took more time to do collect stat than the old one (non partitioned).  When i checked the I/O and CPU that too was increased 3 times than the old table. IS it necessary to collect "Column(Partition)" for Partitioned tables?
 
Regards
Robin
