I ran `iperf3` between two Windows machines and noticed that the speeds were not symmetric. I tested using both the built-in 1-gigabit Ethernet adapters in each machine as well as with 10-gigabit Mellanox ConnectX-2 cards in both machines.
Here's the relevant output. I address the 10-gigabit...
I have 2 mellanox connectx 3 vpi cards. They have been updated to latest firmware and installed one on centos7 and the other on windows 10.
Both cards are on amd threadripper systems with pcie express gen4/3 at 8x or 16x.
On windows I use the latest WinOF drivers.
On linux I use...
Just ran some basic testing on the 3 machines that are going to be linked together via 10Gbe and found some slightly strange performance issues.
This is the kit that is linked together:
Switch - Juniper EX3300 with juniper SR transceivers no vlans or L3 features enabled 1500 MTU
PC1 - Windows...
so I just set up vmxnet3 drivers in OmniOS new install, 151028b on ESXi 6.7U1.
Went to test throughput to see what the difference between the E1000 and vmxnet3 drivers were like, so I fired up iperf3 on pfsense as a server, and sent the most basic test from the OmniOS VM as a client...
