Slow network Performance
Posted: Fri Jul 13, 2018 10:56 am
Hello All,
Kindly I'm facing unusual poor network performance within eve-ng network as the following:
I have bare metal server with 32 GB RAM and CPU Intel(R) Xeon(R) CPU E3-1240 V2 @ 3.40GHz Nic card 1.0Gbps and EVE version 2.0.3-92 community.
I created a lab with Nexus9000v(nxisv9k-7.0.3.I7.27) QEMU Nic (vmxnet3) and connected to it one Windows 7 PC QEMU Nic (tpl(e1000)) and one ESXI 6,7 QEMU Nic(tpl(e1000)) . Also i did configure the jumbo frame on Nexus9Kv.
When i try to upload a file 300MB from win7 PC to local Datastore on ESXi it take one hour ...!!!!
I tried even to upload the file without jumbo frame config , its the same.
the jumbo frame configuration is :
switch(config)#policy-map type network-qos jumbo
switch(config-pmap-nq)#class type network-qos class-default
switch(config-pmap-c-nq)#mtu 9216
switch(config-pmap-c-nq)#exit
switch(config-pmap-nq)#exit
switch(config)#system qos
switch(config-sys-qos)#service-policy type network-qos jumbo
when i do connect the win 7 to ESXI without Nexus9Kv ,using Cloud0 Management interface , i have no problem at all , i can upload the same file 300MB in 5 Min.
any Idea please ...?
