Hi,
The problem is that it is more than just the compression that is the
problem, with modern cpus disk speed is a problem, and compression is
often stream based. For now there isn't enough valid data that this
qualifies as a bug/rfe.
If you decide to try and implement it, and provide data showing that
this is actually a win, please reopen this.
Regards,
Jes

Bug description:
Feature request:
qemu-img multi-threaded compressed image conversion
Suppose I want to convert raw image to compressed qcow2. Multi-threaded conversion will be much faster, because bottleneck is compressing data.
