A logging pipeline processing 500,000 lines per second spends 15-30% of its CPU time on string formatting. An API gateway that constructs JSON error messages from templates allocates millions of temporary strings per hour. Choosing the right formatting library can reduce your service&rsquo;s CPU usage by 40% compared to naive <code>sprintf</code> or <code>std::stringstream</code>.</p>
