[ovirt-users] Re: Poor gluster performances over 10Gbps network

Most probably RH specialists can tune Gluster so well that the libgfapi is uselesss ... who knows. Actually, oVirt and support are 2 completely different topics. Yes, it has it drawbacks, butif it brings significant performance gain.

The qemu process should not use the '/rhev' mountpoints. Also, share your current setup:- disks- hw controller- did you storage align your block devices (hw raid only)- tuned-profile- sysctl settings that are changed- gluster volume options that are changed Best Regards,Strahil Nikolov_______________________________________________ Users mailing list -- users(a)ovirt.org To unsubscribe send an email to users-leave(a)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/FYVQBT4ZYTS...
