I am having an extremely slow network
netperf -H 11.x.x.21
TCP STREAM TEST from 0.0.0.0 (0.0.0.0) port 0 AF_INET to 11.x.x.21 (11.x.x.19) port 0 AF_INET Recv Send Send Socket Socket Message Elapsed Size Size Size Time Throughput bytes bytes bytes secs. 10^6bits/sec 2288 16384 16384 10.16 0.41
I dont understand why 11.x.x.21 is showing
Settings for eth0: Supported ports: [ FIBRE ] Supported link modes: 1000baseT/Full Supported pause frame use: No Supports auto-negotiation: Yes Advertised link modes: 1000baseT/Full Advertised pause frame use: No Advertised auto-negotiation: Yes Speed: 1000Mb/s
Port: FIBRE PHYAD: 2 Transceiver: internal Auto-negotiation: on Supports Wake-on: g Wake-on: g Link detected: yes
tried ethtool -r eth0 but no change at all.
so Manually changed by
ethtool -s eth0 speed 1000 duplex full autoneg off
But still no change in netperf ouptput
ethtool -i eth0
driver: bnx2 version: 2.1.11 firmware-version: bc 5.0.6 NCSI 2.0.3 bus-info: 0000:10:00.0 supports-statistics: yes supports-test: yes supports-eeprom-access: yes supports-register-dump: yes
00:10.0 PIC: Intel Corporation 7500/5520/5500/X58 Physical and Link Layer Registers Port 0 (rev 13)
why auto negotiation put NIC to half duplex and
Why manually changing to Full duplex couldnt solve anything.
