Download Speed : 160.74 MBPS
Upload Speed: 1.93 MBPS
With that being said, it would take me about 15-17 mins just to download 18 GB's for GTA 5 and DOESN'T include installation and an update.
With download speeds that fast why is your upload so slow? I have 30Mbs down and 5 up. If you do a speedtest on your PS3 it will probably only say like 18 Mbs download, pretty sure it can only go so fast.
So it will take you just as long as the rest of us to download 18Gbs to your PS3
I have no idea why my upload is slow.
