Does anyone have any opinions on the yabb cgi forum sofware?

I have one customer using this forum software on their site and they seem to be generating tons of traffic even though their forums is not a popular as a different customers vBulletin forum.

Is it normal for the yabb forum to use so much bandwidth?

Someone else asked this question a short time ago (See this thread (http://www.webhostingtalk.com/showthread.php?s=&threadid=92751&highlight=yabb) To the best of my knowledge, YABB is considered resource intensive, but I've not heard of it being bandwidth hungry. Perhaps with two similar posts though, you may be right.

YaBB is resource intensive, YaBBSE which is a PHP and MySQL port is not.
