Hello list,

I have a few thousand rrd's that I need to run a report against.  I'll need 
to sum the updload and download given x amount of time.  I'll be using 
Python to write this report.

My biggest concern is the performance hit it may take to run this report.  
I was wondering if anyone has any suggestions as to how they would go about 

Right now I'm considering running the report as a cron job during off peak 
hours and storing the results in a format that would be less intensive to 

Any ideas/suggestions are appreciated,
