python program slows over time - feedparser : <p>I have a python program which is running in a loop and downloading 20k RSS feeds using feedparser and inserting feed data into RDBMS.</p>

<p>I have observed that it starts from 20-30 feeds a min and gradually slows down. After couple of hours it comes down to 4-5 feeds an hour. If I kill the program and restart from where it left, again the throughput is 20-30 feeds a min.</p>

<p>It certainly is not mySQL which is slowing down.</p>

<p>Can you please suggest some potential issues with the program?</p>

<p>Thanks</p>
