Sorry all but actually I don't know why it sends so much data. But as you can see, it use port 11110 to send. I think it's because of 10% PoS, it sends so much information to other client. I'm setting up new computer to rebuild wallet to make sure that it's not because of virus in my computer. You can scan wallet, I scan it but it seems that no virus in wallet.

I'll give all new wallet soon.
