That was also my feeling, so nice to get a confirmation!
Another related thing would be to allow qemu-nbd to write compressed
blocks its backing image - today if you use a qcow2 with compression,
any block which is written to gets uncompressed in the resulting image
and you need to recompress the image offline with qemu-img.
Would you have any pointers/documentation on how best to implement this
so both qemu-img and qemu-nbd can use multithreaded compressed writes ?
I'm totally new to qemu block subsystem.

Title:
[Feature request] qemu-img multi-threaded compressed image conversion
Status in QEMU:
New
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.
