Is there really any impact when we commit an update set during business hours?

[Suggy]

As per this article, committing an update set will flush the cashe.

But we have been committing update sets in production throughout the day (since many years) whenever we feel like committing, but never faced any issue till now.

Is there any evidence or is there a way for me to check the performance impact of committing the update set (which causes cache flush as per the documentation?)

@Suggy 

ideally code migration to prod should be done in non business hours so that there is no performance impact.

it varies from customer to customer

My question is not on best practice, but my question is - 

1, How come we are not facing any issues a we are committing the update sets left and right?

2. Is there any evidence or is there a way for me to check the performance impact of committing the update set (which causes cache flush as per the documentation?)

@Suggy 

my responses inline

1, How come we are not facing any issues a we are committing the update sets left and right? -> it depends on what your update set has; if it has complex business logic and workflows etc; it will cause issue as it might break any existing working business logic/process. But that's not defined that you will always face issue.

2. Is there any evidence or is there a way for me to check the performance impact of committing the update set (which causes cache flush as per the documentation?) -> I don't think any way to check that

@Ankur Bawiskar  Thanks for replying.

I am talking about point 'c' in this article What can cause a full system cache flush - Support and Troubleshooting (servicenow.com) which says deploying update sets will cause cache flush. and ofcoure when cache flush happens, everything has to be rebuilt which inturn causes performacne issues.

My question is wrt above point 🙂

Hope atleast now its clear as to what I am asking.
