I work on big tech and average far more lines of production code per day because where my project falls on this spectrum. The biggest thing that I've seen slow things down is scale (both size of codebase as well as users), followed by testing culture. This and a few other factors dictate the rate at which you invest in feature development. Not everything is a heavily undertested behemoth that has hundreds of millions of users. Therefore your experience may differ greatly from others and that means no one has the right experience. Even different roles within an organization making a common product can experience great variance based on subdivision (infra vs platform vs product vs security, seniority, etc).
