A very generic answer, when your latency increases.
Your problem is probably that by the time you notice the latency it's too late

Depending on know scared you are about this issue, HPE provide a performance analysis (paid service) where they will measure the load for multiple days/weeks and provide a detailed performance overview compared to assumed maximum performance of the system. Do one every X months to monitor how the load increases to get an understanding of when you need to stop scale up and start scaling out.
