Also, you could make your script nice like this:

# Set low priority (nice value) for this process...
setpriority( "PRIO_PROCESS", 0, 10 );

while(1) {
  # some code
  # some more code ...
  sleep(300); # it's good to take a nap in the middle of a hard work!
}

The nicier a script, the less greedy it's going to be on system resources. And if it sleeps every once in a while on top of this, it's even more nicier ;)
