   I have used the c_predict_api to build a predict api in the web. but when I conduct the pressure test using 50 requests in 1s, 49 return right result and 1 blocked(10 or 20 requests will also block 1 request). I find that it is blocked in MXPredSetInput and MXPredGetOutputI check the c_predict_api.cc and its include file. I find a unique_lock before a memcpy function and it will be unlock after the memcpy finished in MXPredSetInput and MXPredGetOutput. Why there is 1 request blocked? And how to slove it.
