Hello
we have a slow network performance.
we have cluster with 6 node, HPE DL360 G10 with 2 port 40Gbit network card.
connect with DAC cable to 2 cisco switch with VPC configured.
and LACP
on PVE 8.2.2 we use open vswitch and LACP.
When we run iperf from 1 node to other one we react 30Gbit but not stable the test float from 17 to 30
and we have a lot or retransmit.
we have try to change the DAC camble, port switch
but nothing changes.
any suggestion?
