I have got a Xia-T-hash ASIC Machine, just like this:
http://www.btcgt.com/goods.php?id=8it can mining in slush by "stratum+tcp" normally that is with 1000+Ghashs hashrate,
but by "mining_proxy.exe", it only get a 19+Ghashs hashrate, and the ASIC Machine's Control Panel shows it runs in 1000+Ghashs.

so what is the matter, how to make it runs Fully devoted by "mining_proxy.exe".
