Thanks for Wang's mail, I noticed my 0002 patch was wrong from v3. Here, I attach correct patches. Also I will begin to do some benchmark with higher scale and higher number of users and try to change stats reporting implementation to not affect performance, which I couldn't have not started because of another tasks. -- Yoshikazu Imai
