Hi, I tried disabling the apex driver on my VM and rebooted. Running iperf after the reboot gives the following:

No change or improvement that I can tell, but is this a useful test? I've been trying to get iperf to run on UDP port 4172, but if I run iperf -s -u -p 4172 -l 1300 -i 1 <and> iperf -c 10.2.14.161 -u -p 4172 -l 1300 I get nothing. Is this not a supported operation via iperf?
