Subject: systemd "journalctl" is 1.89sec on ext4, 1.49 min on btrfs
Date: Mon, 27 May 2013 18:21:21 +0200 [thread overview]
Message-ID: <16735484.PAleCPYpY8@noname> (raw)
Dear list,
I have two openSUSE 12.3 systems with kernel 3.9. 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
