ip ranges & perfomance

Is it correct that the cpuload increases with the number of ip adresses? 
Normally I use 213.136.0.0/19 for my homenet. It then has aprox. 50% load. But
when I add only one ip (like 1.2.3.4/32), the CPU load jumps to 100%. 

Why is this? Is every iprange checked against all the rules? (e.g. double the
number of ranges, and the load will also double)
