* Status: Open

----------------------------------------
Try running the Profiler example from documentation page.
(https://docs.ruby-lang.org/en/2.6.0/Profiler__.html)

``` ruby

require 'profile'

def slow_method
  5000.times do
    9999*999999999
  end
end

def fast_method
  5000.times do
    9999+999999999
  end
end

slow_method
fast_method
```



Output:

```

```
By this output, the slow_method and fast_method is called 5000 times? 
I think this is not correct and not match with documentation page
