My question implied to urge you to test with the sender and receiver switched. And compare those results as well. You should end up with 4 sets of transfer speed data. Analysing that should make clear if pulling/pushing is the cause, or if it is the network environment (sender/receiver). Also make sure that the tests are not influenced by other factors (eg. other people doing exactly the same test as yours on the same network/system :)). Doing the tests multiple times during the day may make it more convincing to state your case.
