But branchprediction is not always correct, and some branches are hard to predict.
然而程序转移的预测并不总是正确,并且某些程序转移是很难预测的。

Modern processors practice branchprediction (see Resources), since the underlying algorithm and data have regularities.
现代处理器可以实现程序转移预测(请参看参考资料),因为底层的算法和数据是有规律的。

You can approach this by improving branchprediction in your software, and you can also identify the issues by profiling the application and the kernel for the event BR_MISS_PRED_TAKEN_RET.
