https://bugzilla.suse.com/show_bug.cgi?id=1176309 Bug ID: 1176309 Summary: Encrypted BTRFS root partition is *extremely* slow Classification: openSUSE Product: openSUSE Tumbleweed Version: Current Hardware: Other OS: Other Status: NEW Severity: Normal Priority: P5 - None Component: Kernel Assignee: kernel-bugs@opensuse.org Reporter: dcermak@suse.com QA Contact: qa-bugs@suse.de Found By: --- Blocker: --- I have installed Tumbleweed on a rather powerful machine (Dell Precision 5530). The root file system is btrfs in an encrypted LVM container. The file system performance has unfortunately greatly degraded and is starting to negatively impact my workflow: just downloading a larger image over the internet (download rate <= 12.5MB/s) causes the system load to go up by quite a bit and additional writes to the file system take a noticeable amount of time to finish (e.g. saving a text document takes a few seconds). Unfortunately, I have absolutely no idea how to debug this issue. I used to have compression enabled to save some space on the SSD, but turned it off everywhere via chattr & a full defrag (but that did not really solve the issue). Any help would be greatly appreciated, as I don't really want to reinstall with xfs or ext4 on /. This must be a software/configuration issue, as a colleague has exactly the same machine with btrfs on / as well and never ran into any of these issues. -- You are receiving this mail because: You are the assignee for the bug.
