I'm evaluating a VE LTM Trial, 25 Mbps, BIG-IP 12.1.1 Build 2.0.204 Hotfix HF2
It's running on Hyper-V on Windows Server 2012R2.
When I run ping from the Hyper-V console window of the LTM VM I can measure the following times:
ping -I 172.27.50.1 172.27.50.151 = 7 ms .. 30 ms (pinging from the LTM internal static self-IP to another VM attached to the same Virtual Switch)
ping -I 172.27.50.1 172.27.50.161 = 7 ms .. 30 ms
(pinging from the LTM internal static self-IP to another VM reached through the external network, through a physical switch)
ping -I 172.27.50.1 172.27.51.1 < 1 ms (pinging from the LTM internal static self-IP to the LTM external static self-IP)
ping -I 172.27.50.1 172.27.52.1 < 1 ms (pinging from the LTM internal static self-IP to the LTM management address)
ping -I 172.27.50.1 172.27.51.51 = 2 ms .. 4 ms (pinging from the LTM internal static self-IP to any of the configured LTM Virtual Servers)
pings between the two devices over the HA VLAN are even higher: tens of ms !
I reserved what I judge to be the recommended amounts of vCPU and memory to the LTM VE. I have also disable Virtual Machine Queues in the PhyNICs and in the LTM VNICs.
Has someone suggestions of configurations to check/change, or troubleshooting procedures to reveal the cause of the high latencies above ?
