Project files transfer faster using iQAN Run?

I'm curious as to why an iQAN design project file would transfer to a MD4 faster using iQAN Run, as opposed to transferring it using design. Can someone from Parker comment on this? Is there something I could do differently in Design to get me similar transfer speeds?

Had I known this a few years ago, I could've collectively saved HOURS of time loading programs with lots of graphic elements into machines. I have one program, that when loaded onto a brand new MD4 using Design, would take over 15 minutes. When using Run, the same program transfers in minutes.
