I don&#x27;t know who downvoted you, though I still disagree.<p>If I was writing an embedded system, or a system with soft-to-hard realtime requirements, or one where flat straight line performance was the only requirement that counted, sure, I might ditch or constrain logging.<p>These systems might be common by manufactured volume. But most programmers will never touch one.<p>You&#x27;re probably thinking of I&#x2F;O costs. Again, these aren&#x27;t as a brutal as they used to be -- SSDs swallow bursty writes with aplomb and when those aren&#x27;t enough, log-structured filesystems are good at smoothing out writes.<p>As for myself, in the work I do in my day job, I print out to STDOUT&#x2F;STDERR and let the platform wick those lines away to a central firehose.
