Subject: Btrfs might be gradually slowing the boot process
Date: Fri, 08 Nov 2013 19:35:18 +0100 [thread overview]
Message-ID: <527d2ee689e077.81319728@wp.pl> (raw)
Hello,
I recently noticed that my boot has become slower - it took around 29s, while at the beginning it was ~6s. I thought it was an issue with systemd, because it failed to properly indicate at which stage the slowdown occurred and how long it took. I rolled back to a pretty fresh root subvolume and the boot was fast again. However, after several reboots it started lagging again (10s? preposterous!). I decided to try the *clear_cache* mount option; it was only a guess, but it did speed the boot to
the proper ~6s.
The question is - why? My filesystem is really small - I see no reason for a 5x boot slowdown. Is this a known issue? I will be glad to give any additional details about my fs.
