I have a table ad_tasks , which contains some 7 lakh rows and ard 100 columns .
The entries in the table cannot be pre-determined , they are dynamic . Most of the entires depend on sequence , date and time etc.
The table is not currently partitioned , so DML statements are very slow .
Will partitioning improve the performance ?

thanks for the info
since the data in the table cannot be pre-determined i tried with hash partition on the table with 10 partitions , but still the performance was the same and at times it was slower
also i tried with parallel hint , but the performance was becoming slower , there was not any improvement
any other suggestions?

Continue trying all what you can or imagine.
Maybe at the end you will think to read something about partitioning: when, why...
