我们也可以以EXECUTIONS(执行次数)最多的SQL语句为调优对象。另外,PARSE_CALLS是解析次数,对于此列值最多的SQL语句,我们可以看看是否可以降低语句的解析次数。

分析终结(finalizer)的使用,和他们的执行次数。
Analyze the use of finalizers, including the number of finalizers executed.
Now this happens to be what we would call a linear process, because the number of times I go around the loop is directly related to the size of the argument. If I double 2 the argument, I'm going to double the number of times I go around the loop. If I increase it by five, 5 I'm going to increase by five the number of times I go around the loop.
这恰好是我们会成为,线性复杂度程序的一个例子,因为我要执行循环的次数是,和输入的参数的大小直接相关的,如果我将这个参数乘以,那么我就要将进行循环的次数也乘以2了,如果我把参数加上,那么循环的次数也要加上5了。
