Tom, we have had similar issues where it impacts performance too. What we did was to assign it to a Resource Group to keep it from hurting others while still giving it enough resources to get its work done.

Yesterday afternoon the started task, CDNDM, took from 50-60% of an engine on our z9BC for almost 2 hours while it transferred a large file. This caused us to hit our softcap and affected other tasks in the system. We have the CDNDM task running in our STCLO service class which is set for Vel=50 and an importance level of 4. It was still running at a high DP and grabbed the CPU. I can't understand why a task that is basically transmitting a file over the network should need this much CPU. My only explanation might be that it is compressing the data before putting it on the network and the compression algorithm isn't the most efficient in the world. Has anyone else had this kind of a problem running Connect:Direct? What, if anything, did you do to control it?
