The performance impact on disk throughput should not be significant, as journald still throttles and caches the log messages before flushing them to disk and still forwards them to rsyslog as it did before. The performance impact depends on the workload, and there is a reduction of runtime memory used as well, which helps with throughput by increasing available io cache buffers. -- Regards, Dimitri. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1618188 Title: systemd journal should be persistent by default: /var/log/journal should be created To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/systemd/+bug/1618188/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
