Adding more to this.
Installed today system is running FreeBSD 13.1-RELEASE-p2
VMXNET3 driver is slow on all throughput.
Typically 300 Mb/s slower than any other Linux VM or more on a 1 GB link.
Host system is ESXI 6.7 U3 Dell R720 2 x 2650 v2 128GB ram
VM has 4 Vcpu and 8GB of ram. 2 x nics 1 LAN 1 WAN
ESXO Host has other VM's all linux VM's using VMXNET3 driver get full wire
speed across lan 1GB link.
Tried all the tweaks mentioned to no avail. So will not spam this report with
endless iperf3 tests that are dismal!
Can this be acknowledged and prioritised as a bug.
VMWARE ESXI is one of the most prolific virtualisation platforms it would be
great to see FBSD running well.
Cheers
Tony.
