I think I may have found a way to speed it up.. Don't use your original wallet.dat  let it create a new one  with 0 transactions.(once sync then copy wallet dat to appdata/litedoge folder). I think it may be slowing down processing all the transactions.. I have thousands since I mined and stake since the beginning.. Let me confirm this and ill get back to you.. so far its going way faster..and  the wallet is way more responsive during the sync now..
