When developing a website or web app, nobody wants to spend hours of their time just on speed optimization. The problem is that a fast website is incredibly important and performance is often a deciding factor for its success. Web frameworks like Remix Run were created with the goal of optimizing web performance while keeping their configuration to a minimum ("zero-config"). Nowadays, there are dozens of frameworks available, that help you achieve high speeds.
Unfortunately, the best website load times are of little use to us unless the databases of our apps are lightning fast as well.
