30 Load average with fping script

Hi! I've make a script that gets a list of 200 Ip's and calls another script once per ip in a infinite loop with a pause of 10 seconds. So It calls over 200 times every 10 seconds the second script (that makes a fping). But this cause a load average of 30. I've been reading about this and I undestand that the load average is high because there are a lot of processes (the second script I guess) waiting to be executed. My server has a good performance so, is possible that this high load will become a problem in the future or is it a normal behavior when you run such scripts as I do?

My top info:
Code:
top - 11:27:01 up  2:36,  2 users,  load average: 27.23, 28.56, 28.74
Tasks: 281 total,  32 running, 248 sleeping,   0 stopped,   1 zombie
Cpu(s):  1.4%us, 97.1%sy,  0.5%ni,  0.0%id,  0.0%wa,  0.0%hi,  1.0%si,  0.0%st
Mem:   3115860k total,   588408k used,  2527452k free,   104720k buffers
