测量和基准时间的Ruby方法

问题描述

在Ruby中，如何测量方法以及该方法中的各个语句所花费的时间.如果您看到以下方法，我想测量该方法花费的总时间以及数据库访问和Redis访问所花费的时间.我不想在每条语句之前写Benchmark.measure.红宝石解释器会为我们提供任何帮助吗?

How can i measure the time taken by a method and the individual statements in that method in Ruby. If you see the below method i want to measure the total time taken by the method and the time taken for database access and redis access. I do not want to write Benchmark.measure before every statement. Does the ruby interpreter gives us any hooks for doing this ?

def foo
# code to access database
# code to access redis.
end

推荐答案

您可以使用Time对象. (时间文档)

You could use the Time object. (Time Docs)

例如，

start = Time.now
# code to time
finish = Time.now

diff = finish - start

diff将以秒为单位，作为浮点数.

diff would be in seconds, as a floating point number.

end已保留.
