(From ceph getting max 35 K IOPS for % 100 random write and gluster gave us 15-17K )</div><div>But interesting thing when add additional client to test its get same IOPS with first client means overall performance is doubled , couldn’t test more client but also interesting things is glusterfs do not use/eat CPU like Ceph , a few percent of CPU is used. </div><div><br></div><div>I would like to ask with Openstack , anybody use GlusterFS for instance workload ? </div><div>Anybody used both of them in production and can compare ? Or share experience ? </div><div><br></div><div>Regards</div><div>Vahric Muhtaryan</div></body></html>
