Hi all, I'm struggling with slow network flow on a proxmox vm...
with single core VM I have this throughput
[ ID] Interval Transfer Bitrate Retr
[ 5] 0.00-30.00 sec 2.81 GBytes 806 Mbits/sec 1550 sender
[ 5] 0.00-30.01 sec 2.81 GBytes 805 Mbits/sec receiver
but when I set same VM with four cores (1 socket 4 core or 4 socket 1 core) it slow down
[ ID] Interval Transfer Bitrate Retr
[ 5] 0.00-60.00 sec 3.04 GBytes 435 Mbits/sec 477 sender
[ 5] 0.00-60.01 sec 3.03 GBytes 434 Mbits/sec receiver
I read a lot of thd and I set following tunable with GUI but no luck
net.isr.bindthreads="1"
net.isr.maxthreads="-1"
hw.pci.honor_msi_blacklist="0"
hw.ibrs_disable = 1
net.inet.rss.enabled = 1
vm.pmap.pti = 0
Here env info
HW - Dell Optiplex with realteck nic
Kernel Version - Linux 5.15.74-1-pve #1 SMP PVE 5.15.74-1
CPU - 6 x Intel(R) Core(TM) i5-9500T CPU @ 2.20GHz (1 Socket)
PVE Manager Version - pve-manager/7.3-3/c3928077
Any other VM in proxmox (linux/windows) works with no problem, only this Freebsds has this problem.
Any ideas how to debug/solve this strange behaviour?
No one? :'(
