The performance... of what?

When we talk about performance testing, most people think about the performance of the system in general, or maybe about each of the services or servers. However, there are many inputs we can check when we are checking performance, including the performance of the client’s browser.

Performance metrics

To understand the performance of our system, we should measure the performance of the different components and keep track of them.
