On one of them there's an ext4 partition, while on the other there's a btrfs. I issued a "time journalctl -b --no-pager" command on both systems. This shows the logs from the current boot without passing them to "less". On ext4 (3.9.3): real 0m1.898s user 0m0.291s sys 0m0.105s On btrfs (3.9.2): real 1m49.698s user 0m0.102s sys 0m0.470s Journalctl on btrfs was always this slow, some btrfsck were made on the file system too, but I don't think it was corrupted. On just the first run it's sluggish, after it's fast as the ext4 one. Is it a known issue or can I help somehow debugging this further? Best regards, Ákos Szőts
