Very Slow & Poor Training Neural Network on Broker MT5 Client Terminal

 

i have test my ea using neural network on MT5.The result for training (teach pattern) is excellent in MetaQuotes Server. But when i install several brokers MT5 Client Terminal and run the same ea, the result is very slow & poor. Do there are big gap between brokers servers on input/backdate or large number of data (ie. Price iHigh) or problem on server network?? In one case, the training (teach pattern) not running and the client terminal hanging. Any idea?
