[Bug 707854] Re: encrypted root filesystem with btrfs uses very much CPU

[shawnlandden]

the cpu load of encrypted lvm is proportional the the number of blocks
accessed and written. btrfs does have a checkpointed monotonic writing
that occurs even when the system is completely idle, so this could have
something to do with it.

Title:
  encrypted root filesystem with btrfs uses very much CPU

Status in “btrfs-tools” package in Ubuntu:
  New

Bug description:
  I have installed Ubuntu 10.10 so that it has encrypted root filesystem
  (LVM) with btrfs using alternate installation CD. It seems that btrfs
  is eating up all the CPU power. Load average is constantly over 1.0.
  Is this know problem with btrfs?
