Learn about different kinds of performance, including throughput and response time.
- [Instructor] One aspect of performance…that people might call, I want better performance,…is you want better response time,…you want quicker response time.…There is a minimum acceptable response to something.…When you click the mouse,…it needs to respond to that fast enough.…In a lot of computer systems…that are controlling physical things in the world,…there's a minimum response time…for it to be safe, or acceptable.…
When you push the brake on your car,…it needs to respond…in a certain amount of time to be useful.…If you push the brake and it takes 20 seconds,…that's not really an acceptable brake.…So sometimes the requirement…with respect to time is a deadline…that needs to be satisfied in a certain amount of time…otherwise it's unacceptable.…And earlier than that might be okay.…So minimum time or deadline or similar.…And then there are some times…when you want it to be deterministic,…that is the same amount of time, every time,…where you're sampling something…and you need the sampling to be really pretty regular.…
