Just upgraded to 2.9.0 and actually I see a different issue:
# qemu-img convert -O raw fedora.iso gluster://dalpinfglt04/virt0/fedora6.raw

Hi,
Encryption-at-rest has been supported for some time now. The client is
responsible for encrypting the files with a help of a master key file.
I have a properly setup environment and everything appears to be working
fine but when I use qemu-img to move a file to gluster
I'm using Fedora 24 with version:
qemu-img 2.6.2
glusterfs-api-3.8.12

Issues with qemu-img, libgfapi, and encryption at rest

Thank Stefan,
I compiled both 0.15 and 1.0 and they do not have that problem... but
Fedora package does. Perhaps the way Fedora package was compiled? I'm
going to grab a source package and attempt to compile from that.

Okay, looks like the performance issue started with introduction of
pc-0.15 machine profile in version 1.0.1. I'll narrow the problem down
further.

Executed another test:
F16 KVM -- 15 gbps -- F17 VM
So why is F16 much faster?

Major network performance problems on AMD hardware
Well this is embarrasing. Other Intel KVMs are having the same problem.
The test where I got 20 gbps was actually on a Fedora 16 VM running on
Fedora 16 KVM. I reinstalled both KVM and VM with Fedora 17 and best I
got was 4 gbps.

I ran another test and here is a recap:
F16 KVM -- 20gbps -- F16 VM
F17 KVM -- 4 gbps -- 16 VM
F17 KVM -- 4 gbps -- 17 VM
I'll check F16 KVM with both F16 and F17 VMs. This is all done on my
Intel core i3.

Public bug reported:
Hi,
I am experiencing some major performance problems with all of our beefy
AMD Opteron 6274 servers running Fedora 17 (kernel 3.4.4-5.fc17.x86_64,
qemu 1.0-17). The network performance between host and the virtual
machine is terrible:
# iperf -c 10.10.11.22 -r
I would also like to add that a VM running Windows 2008 R2 is having the
same identical problem too.
