Project packing problem

Hi guys! Have a problem with packing the game. I wish to compare building time of some engines, and i started from UE4. I have install it from Launcher, create new TopDown template project without any starter content and click to pack it for x64 systems. It packing over an 1.5 hour at this moment and stuck on this line:
LogFileHelpers: Editor autosave (incl. sublevels) for ‘/Game/TopDownBP/Maps/TopDownExampleMap’ took 0.068

I know, my PC specs not top, but it’s an empty project O_o Maybe i need to change some settings or something else. I need yours help, cuz i try to choose between CE5 and UE4 (UE4 i like more than other engines).

P.S. My PC conf:
AMD Athlox x2 270 (3.400 Ghz)
Kingston HyperX 8Gb DDR3 1600 PC3-12800
NVIDIA GTX 650 1Gb 192 bit
Seagate Barracuda 1 Tb 5400, 16 Mb
