You mean like bandwidth utilization? Hmm, ok -- didn't know that. I'd think that millions of 142k messages flying around at any given second would be worse, but I am not in the know about these things.
Sven is a mass-mailer, which is bad enough.
Nachi floods the network with a constant stream of pings from every infected machine. That's much more degrading to a network than mass emailing.
On top of that, the spam traversing Adelphia's network is probably more demanding than Sven mailings anyway. I average 100-150 spam emails per day and I haven't received the Sven worm in quite some time now.
