Speed up journald

Is there any way to improve performance on jounald?

System boots fast but cannot helping thinking it could go quicker?

Re: Speed up journald

Would this get faster if /var/log/journal is smaller? How large is it right now for you? I don't know if it gets faster if it's smaller, but you can tweak limits in /etc/systemd/journald.conf. You can do for example "SystemMaxUse=1G", "MaxFileSec=1week".

Re: Speed up journald

@graysky you can always go faster....

Have set max use too 50M and have cleared out journal (was 520mb).. Not changed other max file yet.
