尽管有了管理连接池的资源管理器，但是还不能保证ejb层具有最优性能——还有一些设计考虑事项！
The fact that you have resource managers that manage your connection pools does not guarantee optimum performance from the EJB layer — there are some design considerations as well!
通过实验表明，此方法在性能，输出结点数量上都有优势，而且在主存空间变化时，此方法仍具有明显的最优性。
An experiment shows that the method has advantage in performance and outputted node number, and moreover, when the space of the main memory is changed, the method still has notable optimality.
这主要是由于支持向量机目标是在小样本情况下追求学习的最优性能，更加符合实际情况，从而在现实中具有更好的推广能力。
SVM usually has a better performance than the conventional methods because it is to acquire the best function when the number of training data is small which is often met in true-life.
