Parsing thousands of feeds

I need to parse +4000 feeds.. how can I do it using feedparser? it's possible to set multiple cron jobs? [that could be helpful?]
maybe I can parse selected feeds in each cycle [based in their updating frequency].. but, again, how can I do something like this? this module is the best for massive feed aggregation -thinking in even more feeds-?

I don't know if here is the place for this issues, excuse any inconvenience.

thank you
