Changing your page pool really helps. I had trouble figuring it out at first being all noobish. You can also overclock you processer. Wing still isnt blazing fast, but its much improved.

You can get the pagepool and overclocking cab here as well as instructions. Make sure with the pagepool that you have your wing synced to the PC. run the cab from your phone and the pagepool bat. from your pc. soft reset.
Good Luck
