Virt settings are those: [root@ovirt1 slow]# cat /var/lib/glusterd/groups/virt performance.quick-read=off performance.read-ahead=off performance.io-cache=off performance.low-prio-threads=32 network.remote-dio=enable cluster.eager-lock=enable cluster.quorum-type=auto cluster.server-quorum-type=server cluster.data-self-heal-algorithm=full cluster.locking-scheme=granular cluster.shd-max-threads=8 cluster.shd-wait-qlength=10000 features.shard=on user.cifs=off cluster.choose-local=off client.event-threads=4 server.event-threads=4 performance.client-io-threads=on I am using cluster.choose-local set to on ,as my Network is far slower than the bricks. Another optimization you can consider is to test with different values of event-threads , shd-max-threads and maybe low-prio-threads - but this is valid for Fast SSDs/NVMEs. Of course, it's reasonable to have a production environment that is separate from test :) Best Regards, Strahil Nikolov В четвъртък, 22 октомври 2020 г., 14:00:52 Гринуич+3, suporte@logicworks.pt <suporte@logicworks.pt> написа: Hello, For example, a window machine runs to slow, usually the disk is allways in 100% The group virt settings is this?: performance.quick-read=off performance.read-ahead=off performance.io-cache=off performance.low-prio-threads=32 network.remote-dio=enable features.shard=on user.cifs=off client.event-threads=4 server.event-threads=4 performance.client-io-threads=on ________________________________ De: "Strahil Nikolov" <hunter86_bg@yahoo.com> Para: "users" <users@ovirt.org>, suporte@logicworks.pt Enviadas: Quarta-feira, 21 De Outubro de 2020 19:22:14 Assunto: Re: [ovirt-users] Improve glusterfs performance Usually, oVirt uses the 'virt' group of settings.
