"Evolution is a process of constant branching and expansion."

Scalability and performance are not the same things:
"The terms "performance" and "scalability" are commonly used interchangeably,
but the two are distinct: performance measures the speed with which a single request can be executed, while scalability measures the ability of a request to maintain its performance under increasing load. For example, the performance of a request may be reported as generating a valid response within three seconds, but the scalability of the request measures the request's ability to maintain that three-second response time as the user load increases."
