Re: Why are virsh vol-upload/vol-download so slow?
...)
Use I/O vector (iovec) instead of one huge memory buffer as suggested
in https://bugzilla.redhat.com/show_bug.cgi?id=1026137#c7. This avoids
doing memmove() to big buffers and performance doesn't degrade if
source (virNetClientStreamQueuePacket()) is faster than sink
(virNetClientStreamRecvPacket()).

Why are virsh vol-upload/vol-download so slow?
I was interested in using 'virsh vol-upload' and 'virsh vol-download',
rather than mucking about directly with the filesystem. But while
simply copying the image is relatively quick:
# ls -l /var/lib/libvirt/images/centos-7-cloud.qcow2
-rw-r--r--. 1 qemu qemu 1004994560 Apr 15 2015 centos-7-cloud.qcow2
# time cp /var/lib/libvirt/images/centos-7-cloud.qcow2
