True.

The problem is not how much swap is in use (as long as it doesn't run 
out), but rather how much swap _traffic_ occurs. If it's a little and / 
or occasional, there's no problem. If it's a lot and / or ongoing, it's 
going to make your system slow and CPU utilization low. That's 
called "thrashing."
