Libgfapi bypasses the context switching from User space to kernel to user space (FUSE) , so it gets better performance. I can't find the previous communication ,so can you share your volume settings again ?

Write performance still bad. Am I right that this look then more like a glusterfs issue and not something what need to be changed on ovirt (libgfapi) or on VMs. Changing tcp offloading did not make any difference. - ethtool --offload enp1s0f0 rx off tx off - ethtool --offload enp1s0f0 rx on tx on MTU 9000 is fine and ping is working. - ping -M do -s 8972 another-gluster-node _______________________________________________ Users mailing list -- users@ovirt.org To unsubscribe send an email to users-leave@ovirt.org Privacy Statement: https://www.ovirt.org/privacy-policy.html oVirt Code of Conduct: https://www.ovirt.org/community/about/community-guidelines/ List Archives: https://lists.ovirt.org/archives/list/users@ovirt.org/message/23FIY4DLT5CBZF...
