It looks like qcow2_write_compressed() has been removed and turned into a qemu co-routine in qemu 2.8.0 (released in December 2017) to support live compressed back-ups. Any pointers to start working on this? We have servers with 128 CPUs and it's very sad to see them compress on a single CPU and take tens of minutes instead of a few seconds.. :)

Multi- threaded conversion will be much faster, because bottleneck is compressing data. To manage notifications about this bug go to: https://bugs.launchpad.net/qemu/+bug/601946/+subscriptions
