rsync is hard on networks???????????

Is there any truth to this? I find it hard to believe -- most of the time rsync is tunneled over ssh which seems well enough abstracted from an optimal traffic generation mechanism that i would seriously doubt it's able to outcompete other programs for network resources in a meaningful way ... perhaps this observation evolved because there are a lot of networks that have traffic shaping rules for ssh? unfortunate effects of traffic shaping rules for ssh + low bandwidth connection + rsyncs happening over ssh + an administrator logged into an ssh port via the low bandwidth link

could maybe produce this observed (but non-sensical?) correlation?
