The lag is .3 second delay between client and server if we're talking about same thing, but thats on all platforms as its the way the game was built. Oh I still get limited characters on screen at a time like in Modhoa but they load super quick and draw distancing is greatly improved, but the limited characters/NPCs etc is hardware limitations - not complaining though as im just amazed they got an MMO like this to work on a console at all :)
EDIT: Yeah its very useful for playing games of HDD/PSN download, even games with big installs are impoved e.g. MGS4 (like 2 second load screen), GTAIV (GTAV I guess), trust me if you cant afford a PS4 for a while an SSD in the PS3 is a good performance boost.
