Battleping is a VPN service and probably wont work on PS3 unless you have the technical know-how and desire to void your warranty to basically turn your PS3 into a computer. If you've already tried the lowest possible graphic settings with no improvement, that wont work either (you might get an Frames-Per-Second boost and feel that everything is smoother, but try a popular FATE during the prime-time of your server, as well as a popular tome dungeon during the cap rush at reset, and one primal fight such as Titan and see if it holds). Connecting directly by cable to router rather than wireless might alleviate some of it, as well as resetting the router and port forwarding the ports that FFXIV uses (I got no change from this).
