You do not get double the bandwidth from a LAG, except under the most ideal circumstances; you probably get an increase in overall traffic, but usually not at all for something like NFS (which uses a single TCP socket for communication). LAGs don't balance or round-robin traffic; they hash some selection of packet info (sometimes just source/destination MAC, sometimes adding IP, sometimes also TCP/UDP src/dest port) and select a LAG member to use based on the hash. All packets of a single stream go down the same LAG member, because otherwise you introduce jitter and out-of-order packet arrival. Also, 10G has lower latency than 1G, which helps NFS performance as well. -- Chris Adams <li...@cmadams.net> _______________________________________________ users mailing list -- users@lists.fedoraproject.org To unsubscribe send an email to users-le...@lists.fedoraproject.org Fedora Code of Conduct: https://docs.fedoraproject.org/en-US/project/code-of-conduct/ List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/users@lists.fedoraproject.org Do not reply to spam, report it: https://pagure.io/fedora-infrastructure/new_issue
