Nope not just you, 1k hosts and the system was almost unusable on a  
dual amd mp2800, in the end I wrote my own monitoring system running  
from a db backend and achieved the same results as nagios with 1/50th  
the actual load whilst also keeping historical data in a db.

Nagios is great if you need the multitude of host checks  
(ssh,apache,mysql,postgres, etc etc) for a core network, but if  
you're just after something to check host connectivity it may not be  
the right tool for the job.
