1, if Yii connected to a number of different databases at the same time, then the comparison, this you in addition to the asynchronous queue to accelerate there is no good way, if it is a master more from, yii in the execution of the transaction at the time to always execute SQL on the main;
2. Ibid.
3, you can consider a master multi-slave mode, execute the transaction quickly. If it is three different business systems, and demand data must be real-time, hehe. I can assume that the execution time is 0, the optical connection time, not acceptable ...

Whether there is data to locate troubleshooting issues. You can try to pinpoint where the problem is.

You might consider splitting the business with a queue.
