I think that the bottleneck could be the disk. You are saving to a HDD, right?
If you have a SSD by chance, close the app (and make sure it's closed), move the data folder to the SSD, make a symlink there and fire it up again. And when you are sync-ed, move the data back where you want it to be.
(Of course back up the sensitive data)
you didnt understand its fresh server i just installed Bitcoin-QT i want to sync it fast
