When performance testing can be started?

As a fresher or new buddy in the performance testing world, there was a common question "When we can start Performance Testing?". Although I would not deny to start the first phase of PTLC i.e. requirement gathering at the initial phase of SDLC or when a beta code is ready. The answer to the above question is very well narrated by Federico Toledo in an article along with the methodology. You may skip the initial part of the article if you are aware of performance testing and methodology definitions. Yes, the bottom part and the conclusion is readable.

Generally, networking terms like latency etc are difficult to understand with an example, so refer to this post and get the understanding of Performance Testing basics.
