XG-7100 10 gbe throughput issue
-
Your testing too pfsense? Test THRU pfsense..
iperfclient -- pfsense -- iperfserver
-
For testing throughput you should be testing through the firewall, not with one end on the firewall. Not that I think that's exactly why you are seeing what you are seeing, but that methodology is wrong.

^exactly... When he said all he saw was iperf using up cpu at the top of his list when you asked him to check top when running iperf I take it that he is testing to pfsense..

Let me provide some context. I have 2 machines with 10 Gbe networking capability through sfp+. A TrueNAS Server and the Netgate XG 7100. In about 3 weeks, I will add a virtualization server that also has 10 Gbe sfp+. I am just in the process of setting up the systems for a small business with high throughput needs. The "in rack" networking is at 10 Gbe while for now all the clients are 1 Gbe. What I wanted to test was the throughput within the rack. Since I didn't have another iperf3 server capable of 10 Gbe I used the pfsense box. The other alternative would be to test the throughput to multiple 1 Gbe clients but I don't have that option right now either. Hence the test to the pfsense box. Help me out here but my thought was that if I can't get 10 Gbe (or close) to the pfsense, its unlikely that I will get it through the pfsense to the virtualization server when I set it up in a month's time.

Right now we don't know that it's not the switch. Have you tried directly connecting them?
-
Agreed. I am working on ruling that out. What I plan to do is attach the TrueNAS directly to the XG 7100 and run the same test to rule out a switch problem but the pfsense will still be the iperf3 server.
-
I have a couple units here. It'll take me a bit to get the test set up. It's going to be iperf3 between an XG-2758 and XG-7100. If anything is the limiting factor there it should be the 2758.
-
That would be great. Thank you.

Today, I attached the TrueNAS directly to the XG 7100 with a DAC sfp+ cable and ran an iperf3 test. The transfer rate was 2.2 Gbps. Twice what is was with the switch between them but still way below what I would have expected. Any suggestions would be greatly appreciated.
-
Clarification on the immediately prior post. On a direct connection of the TrueNAS to the XG 7100, I get a transfer rate of 2.2 Gbps if the XG 7100 is the client. It is ~ 1 Gbps if the XG 7100 is the server. That seems to me to rule out the Switch as the bottleneck. I got exactly the same rates with and without the switch in the path.
-
I was seeing the same sort of thing but it looked like it was the iperf3 process on the firewall itself becoming CPU bound.
That brings us back around to testing through the firewall not to/from the firewall.
-
Thanks for that Derelict. I guess I will just have to wait until the new server arrives and see what happens then. Appreciate your help.
