On cXR I had a similar experainces to Erik, copying via a network protocol was very slow (circa 1-2 hours) but copying via USB was significantly faster (just minutes). I recently upgraded from eXR 6.5.2 to 6.5.3 and pushed the files using SCP to the router from a jump box, which was on the same LAN as the management interface on the RSP. It was copying at 100Mbps (the speed of the OOB switch) so I think in eXR these issues are more or less fixed.
