是否可以计算代码执行步骤?(Is it possible to count code execution steps?)

是否可以报告由一段代码执行的计算数量?

我知道基准测试gem会报告运行时,但不相信它会计算完成的计算次数。

为了清楚起见,我正在谈论处理器级别。


Is it prossible to report how many calculations where executed by a section of code?

I know the benchmark gem will report on runtime, but don't believe it'll count the number of calculations done.

Just to be clear, I'm talking about at the processor level.

最满意答案

您可以创建一个函数或存储过程来执行此操作。 另一种选择是使用case语句。

You can create a function or stored procedure to do that. Another option is to use a case statement.
