 I re-run them with a different model?  I can do that this weekend if I
 know what to simulate.

 The "IM" client simply fetches a 1 KiB file every [1,5] seconds, and will
 not create your "sparse exit stream" situation as I understand it, since
 it will be reading and writing approximately the same amount.

 We could configure a new client type that fetches 1 byte files at a time
 from a web server, though not from several streams at once. Will that give
 you the effect you are looking for, or will there not be enough data
 transferred there to make a difference? (I suspect the latter...)
