it took 30-60 minutes for me to be able to play anything but a quick game in nba2k14. It is a problem, especially since most really don't understand the point of installing when you have to put the disc in every time.
Fixing it would probably be a combination of a firmware update and better organisation of installation files, it needs to further prioritise certain chunks of data over other chunks of data.
Sony probably looked into it quite a lot already due to all the flak they got with install times on the PS3 while Microsoft didn't have to bother with install times with the 360 for the most part and thus probably didn't plan ahead and get this installation method totally efficient.
