[Gluster-users] QEMU-GlusterFS native integration demo video

[Fernando Frediani (Qube)]

Hi Bharata
Thanks for this, very useful.

Would you be able to specify tests with mainly reads and writes. As far as I know there is a big hit and poor performance on writes in normal fuse mounts.
Are you using IOmeter or bonnie ?

Seems the results with fuse and the native qemu-glusterfs are pretty similar, am I right ?

Regards,

Fernando

Fernando,

In the video I was using a single node system (local brick). However I have tested QEMU-GlusterFS with 2 node scenario too.

I have some performance numbers that compare the QEMU-GlusterFS native integration with QEMU-GlusterFS FUSE mount. Were you looking for anything different ?

I don't have numbers for qcow2 or for create, but have numbers for reads for raw files.

FIO numbers for read can be found here:

http://lists.gnu.org/archive/html/gluster-devel/2012-08/msg00063.html

I am planning to publish more numbers for other scenarios (qcow2 and writes etc) in future.

Regards,
Bharata.
