H Stefan, only for write ? or also read ?
I'll try to reproduce on my test cluster. ----- Mail original ----- De: "Stefan Priebe" <s.pri...@profihost.ag> À: "qemu-devel" <qemu-devel@nongnu.org> Envoyé: Dimanche 15 Février 2015 19:46:12 Objet: [Qemu-devel] slow speed for virtio-scsi since qemu 2.2 Hi, while i get a constant random 4k i/o write speed of 20.000 iops with qemu 2.1.0 or 2.1.3. I get jumping speeds with qemu 2.2 (jumping between 500 iops and 15.000 iop/s). If i use virtio instead of virtio-scsi speed is the same between 2.2 and 2.1. Is there a known regression? Greets, Stefan
