I've about 150 different IPs like ...
iptables -A block -s 155.161.173.128/26 -j ACCEPT
iptables -A block -s 155.161.194.128/26 -j ACCEPT

So, to make it easy for testing, you can do a loop like this ...
for((i = 1; i < 100; i++))
do
iptables -A block -s 10.0.0.$i -j ACCEPT
done

I'm running ThinkPad X61. Dual core T9300, 2.5GHz, 4GB RAM, 256GB SSD.
No load as I was not running anything else, and X not running.

Thanks,
Jeff.
