Installing pfSense on XG105Rev3
-
@stephenw10
Hi there, thanks for the reply, I tried that but the cpu is not maxing out. It sticks at around 20% while the test is running -
On both cores?
-
@stephenw10
Hi there, will check this again soon but yes afaik it was on both cores 20% usage. -
Hmm, I would expect more usage than that on that CPU at 600Mbps.
-
@stephenw10 hi there i checked again and I am at 91%. sorry for the misinformation around there.
-
@stephenw10 but the main problem remains: why is the network speed between 2 networks (2 nics) so slow?
when i check iperf3 from igb1(192.168.178.0/24) to igb2(172.16.24.0/24) its super super slow (3,1 MBit/s) and the CPU usage on the pfSense is low (about 5%, peek to 20/25%).
Is there something i can do/tune/change in the setup? -
That sort of throttling is almost certainly one of the NICs not linked correctly. When you see less that 100Mbps on what should be a Gigabit link it's usually because the autonegotiation has failed and something is running at the fallback default of 100M half-duplex. So check the ifconfig output on pfSense and check the link speed at each host.

@stephenw10 i forced it via pfsense to 1000Tbase Full duplex but still the same issue:

My switches even say, that the Uplink to the router (pfsense) is 1000M. I forced it but still no change.
-
@sysadminfromhell Well, have you checked the obvious?
Cables/patch cords.
There isn't much to tune in any case and intel cards and pfsense are considered perfect matches -
Hmm, was anything forced before? Forcing the link speed is usually the cause of these problems. Gigabit Ethernet requires autoselect
-
@stephenw10 no nothing was forced before.
-
@netblues yes i checked everything and even changed the cables of the hosts and the switch to the pfsense but the problem remains
-
Errors shown on the interfaces?
Throttling to 3Mbps almost has to be something at layer 1....
-
@stephenw10 where I can check that?
-
In Status > Interfaces is easiest.
-
@stephenw10 no errors in/out
-
@stephenw10 good morning, I changed the igb from 2 to 3 to check if the port is damaged/broken but the problem remains the same. I will do the following today:
As this subnet has the same as the ISP router gives the pesense gives igb0 (172.16.1.10/29) I will change this subnet from the ISP to something else like 10.0.1.0/29 or something like this and see if this problem remains. I do not know if this interfering in any way but let’s see, shall we?Edit: I updated the subnet from the ISP router to: 10.0.1.252/30 so the igb0 now has the IP 10.0.1.254. I testet the performance and Download is now OK (300 MBit - 980MBit) but Upload remains the same problem: 3,14MBit/s.
-
Hmm, OK changing the WAN subnet should make absolutely no difference to traffic between internal subnets unless there were a conflict caused by dhcp.
So that suggests something is not configured as expected. Like those interfaces are somehow linked via some other path. Are they bridged? Are they even direct ports on that device?Steve
-
@stephenw10 so haft day through, i found the problem.
It was a faulty NIC driver on windows maschine what made the Upload internal so slow.
I do not know why but i ended up reinstalling windows 11 and now everythings looks fine:.\iperf3.exe -c 172.16.24.100 -t 10 Connecting to host 172.16.24.100, port 5201 [ 4] local 192.168.178.110 port 64862 connected to 172.16.24.100 port 5201 [ ID] Interval Transfer Bandwidth [ 4] 0.00-1.00 sec 113 MBytes 950 Mbits/sec [ 4] 1.00-2.01 sec 74.9 MBytes 624 Mbits/sec [ 4] 2.01-3.00 sec 68.5 MBytes 579 Mbits/sec [ 4] 3.00-4.00 sec 93.1 MBytes 781 Mbits/sec [ 4] 4.00-5.00 sec 113 MBytes 947 Mbits/sec [ 4] 5.00-6.00 sec 113 MBytes 949 Mbits/sec [ 4] 6.00-7.00 sec 113 MBytes 949 Mbits/sec [ 4] 7.00-8.00 sec 113 MBytes 949 Mbits/sec [ 4] 8.00-9.00 sec 90.4 MBytes 759 Mbits/sec [ 4] 9.00-10.00 sec 76.2 MBytes 639 Mbits/sec - - - - - - - - - - - - - - - - - - - - - - - - - [ ID] Interval Transfer Bandwidth [ 4] 0.00-10.00 sec 969 MBytes 813 Mbits/sec sender [ 4] 0.00-10.00 sec 969 MBytes 813 Mbits/sec receiver.\iperf3.exe -c 172.16.24.100 -t 10 -R Connecting to host 172.16.24.100, port 5201 Reverse mode, remote host 172.16.24.100 is sending [ 4] local 192.168.178.110 port 64879 connected to 172.16.24.100 port 5201 [ ID] Interval Transfer Bandwidth [ 4] 0.00-1.01 sec 45.1 MBytes 373 Mbits/sec [ 4] 1.01-2.00 sec 107 MBytes 909 Mbits/sec [ 4] 2.00-3.00 sec 112 MBytes 942 Mbits/sec [ 4] 3.00-4.00 sec 112 MBytes 942 Mbits/sec [ 4] 4.00-5.00 sec 112 MBytes 942 Mbits/sec [ 4] 5.00-6.00 sec 101 MBytes 846 Mbits/sec [ 4] 6.00-7.00 sec 53.2 MBytes 446 Mbits/sec [ 4] 7.00-8.00 sec 54.7 MBytes 459 Mbits/sec [ 4] 8.00-9.00 sec 112 MBytes 942 Mbits/sec [ 4] 9.00-10.00 sec 112 MBytes 942 Mbits/sec - - - - - - - - - - - - - - - - - - - - - - - - - [ ID] Interval Transfer Bandwidth Retr [ 4] 0.00-10.00 sec 923 MBytes 774 Mbits/sec 4 sender [ 4] 0.00-10.00 sec 922 MBytes 774 Mbits/sec receiverThanks for the help!
