I assume by 'warm cache' you mean that I had used the decimal module before 
and not switched the machine off before trying the above exercise.

In my case, the machine was switched off before I started. I switched it on 
and executed the above steps.

To be slightly more precise, instead of 'the blink of an eye', I estimate it 
was between 250-500 ms. If I close the interpreter and start it up again, it 
takes maybe 100-200ms.

Just to be sure, I switched the machine off and on again, and repeated the 
exercise. Starting the interpreter for the first time takes 1.5 - 2 seconds. 
Importing decimal for the first time takes less than 500ms.
