Purge script became very slow after speedy execution for couple of days

Hi,

WE are purging some old data by scheduling the purge script.

This script runs continuously over a day to purge old records to control the db growth.

Initial ly for  3-4 days, the purge script execution performance was optimum with purging 5 million records.

After that,it has become immensly slow,deleting only 0.2 million records.

Due to this ,db has again started growing. 

Your suggestions/views/thoughts on how to make it faster again are highly appreciated.

Howdy, Stranger!
