With the ATI bug I was hitting earlier fixed, only my btrfs partition continues to show high cpu usage for some operations. Rsync, git pull, git checkout and svn up are typicall operations which trigger the high cpu usage. As an example, this perf report is from using git checkout to change to a new branch; the change needed to checkout 208 files out of about 1600 total files. du(1) reports

The options -x -v gave me an error that no such option so I ruined it with —debug option. root@ny2proxd03:/var/lib/vz/images/100# virt-resize --expand /dev/sda3 vm-100-disk-1.qcow2 vm-100-disk-1.qcow2.resized --debug command line: virt-resize --expand /dev/sda3 vm-100-disk-1.qcow2 vm-100-disk-1.qcow2.resized --debug Examining vm-100-disk-1.qcow2 ... libguestfs: trace: add_drive
