If you think there is an actual network problem, you could I suppose try 
exploring that with netperf or iperf.  It seems unlikely that the 
network could retain a "memory" of a previous transfer to cause a 
subsequent, non-overlapping transfer to run more slowly.

The logs on the compute node(s) will show how long it took to actually 
retrieve the image yes?
