I/O waits hurting anyone?

I have a process that executes a lot. Over 6 days it's executed 1.3 million times. The elapsed time per call averages 0.8 seconds, and the I/O wait time per call averages 0.7 seconds.

In other words, it spends most of its time waiting.

I'll look into all that... my question is more general: am I right in saying that the I/O waits don't load the system in any way and don't hurt any processes besides the one that is waiting?

Thanks in advance!
