Hello,
After the latest upgrade and reboot to load the latest kernel, i’m facing a high decrease of network performance.
I’ve removed each interface from bond to ensure that there is no faulty cable, destroyed the bond and connected with only one interface and there is no improvement.
iperf stats:
[ ID] Interval Transfer Bandwidth
[ 3] 0.0- 1.0 sec 1.50 MBytes 12.6 Mbits/sec
[ 3] 1.0- 2.0 sec 512 KBytes 4.19 Mbits/sec
[ 3] 2.0- 3.0 sec 9.62 MBytes 80.7 Mbits/sec
[ 3] 3.0- 4.0 sec 19.0 MBytes 159 Mbits/sec
[ 3] 4.0- 5.0 sec 22.5 MBytes 189 Mbits/sec
[ 3] 5.0- 6.0 sec 26.0 MBytes 218 Mbits/sec
In my setup I have a LACP bond with 2x10G network interfaces:
lspci |grep Ethernet

ifconfig ens15f0|grep mtu
ens15f0: flags=6211<UP,BROADCAST,RUNNING,SLAVE,MULTICAST> mtu 9000
Installed the latest drivers for the network card, no improvement.
modinfo ixgbe|grep -i version
version: 5.0.4
srcversion: BA7E024DFE57A92C4F1DC93
vermagic: 4.8.7-1.el7.elrepo.x86_64 SMP mod_unload modversions
Any idea what caused this? Should I update from the testing repo?
Thanks,
Alex
