NOTE: after the last patch, this may no more be effective, due to Blizza fixing some stuffs in the net code.
I've found this trick and seems to work wery well (at least usually im around 300-350ms, now im at 150ms!)

Type "regedit" in windows "run.." dialog to bring up registry menu
Then find:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\Interfaces\
There will be multiple NIC interfaces listed in there, find the one you use to
connect to the internet, there will be several interfaces listed (they have long
names like {7DBA6DCA-FFE8-4002-A28F-4D2B57AE8383}. Click each one, the right one
will have lots of settings in it and you will see your machines IP address listed
there somewhere. Right-click in the right hand pane and add a new DWORD value, name
it TcpAckFrequency, then right click the entry and click Modify and assign a value
of 1.
You can change it back to 2 (default) at a later stage if it affects your other TCP
application performance. it tells windows how many TCP packets to wait before
sending ACK. if the value is 1, windows will send ACK every time it receives a TCP
package.

PS: not sure if restart is needed after this
