Bottlenecks Quote by Eric S. Raymond
“Rushing to optimize before the bottlenecks are known may be the only error to have ruined more designs than feature creep. From tortured code to incomprehensible data layouts, the results of obsessing about speed or memory or disk usage at the expense of transparency and simplicity are everywhere. They spawn innumerable bugs and cost millions of man-hours - often, just to get marginal gains in the use of some resource much less expensive than debugging time”

Prioritizing premature optimization without understanding bottlenecks leads to complex, buggy systems; simplicity and transparency should precede performance tweaks.
In simple terms: Fixing performance before knowing real limits creates messy code.
