Single log line is 49KB+ (ext4) / 110KB+ (btrfs) of systemd-journald disk writes

Unexpected performance bottlenecks or high I/O costs? A single log line from systemd-journald can surprisingly generate massive disk writes—up to 110KB+. This inefficiency directly impacts application performance, especially in I/O-intensive services and cloud environments. For software engineers and AI practitioners, understanding this overhead is critical for optimizing system design, resource management, and keeping infrastructure lean.
