In our lab I can say that we roughly peek ~40 MiB/sec reading a single vm and the rest of our components(after the read from vmds) have no problem dealing with that - i.e buffering -> converting -> writing to imageio -> writing to storage So, in short, examine the read-rate from vm datastore, let us know, and please specify the versions you are using. _______________________________________________ > Users mailing list -- [email protected] > To unsubscribe send an email to [email protected] > Privacy Statement: https://www.ovirt.org/site/privacy-policy/ > oVirt Code of Conduct: > https://www.ovirt.org/community/about/community-guidelines/ > List Archives: > https://lists.ovirt.org/archives/list/[email protected]/message/KQZPRX4M7V74FSYIY5LRUPC46CCJ2DCR/ >
