Q4) Server (avg response 500ms) <---> Security Gateway (timeout is 100ms) <---> Client (React UI) This is a setup where the average server response time is 500ms, but the organization's security gateway is 200ms. You can't change the security gateway. And also you can't greatly scale the server.. (ex by adding more machines and loadbalancing them, introducing caches like Redis for faster lookup etc to reduce the response time from 500ms). So the avg response time 500ms is fixed. You have only control over the client and server. And can make small changes.
