Hello! Sorry for the English, google translator did it. : D There is a speed problem with the internal network. The connection is 10g, but the speed is only 4-5g … Debian server - ipfire [root @ wrouter ~] # iperf3 -c 192.168.2.241 Connecting to host 192.168.2.241, port 5201 [5] local 192.168.2.1 port 36002 connected to 192.168.2.241 port 5201 [ID] Interval Transfer Bitrate Retr Cwnd [5] 0.00-1.00 sec 435 MBytes 3.64 Gbits / sec 0 503 KBytes [5] 1.00-2.00 sec 552 MBytes 4.63 Gbits / sec 0 611 KBytes [5] 2.00-3.00 sec 542 MBytes 4.55 Gbits / sec 0 509 KBytes [5] 3.00-4.00 sec 549 MBytes 4.61 Gbits / sec 0 648 KBytes [5] 4.00-5.00 sec 562 MBytes 4.72 Gbits / sec 1,503 KBytes [5] 5.00-6.00 sec 568 MBytes 4.76 Gbits / sec 0 543 KBytes [5] 6.00-7.00 sec 572 MBytes 4.81 Gbits / sec 0 535 KBytes [5] 7.00-8.00 sec 570 MBytes 4.77 Gbits / sec 0 628 KBytes [5] 8.00-9.00 sec 568 MBytes 4.77 Gbits / sec 0 526 KBytes [5] 9.00-10.00 sec 569 MBytes 4.76 Gbits / sec 0 571 KBytes * * * [ID] Interval Transfer Bitrate Retr [5] 0.00-10.00 sec 5.36 GBytes 4.60 Gbits / sec 1 sender [5] 0.00-10.00 sec 5.36 GBytes 4.60 Gbits / sec receiver the speed is acceptable as a server but not perfect ipfire server - debian client [root @ wrouter ~] # iperf3 -s * * * Server listening on 5201 (test # 1) * * * Accepted connection from 192.168.2.241, port 36042 [5] local 192.168.2.1 port 5201 connected to 192.168.2.241 port 36044 [ID] Interval Transfer Bitrate [5] 0.00-1.00 sec 779 MBytes 6.53 Gbits / sec [5] 1.00-2.00 sec 1.10 GBytes 9.42 Gbits / sec [5] 2.00-3.00 sec 1.10 GBytes 9.41 Gbits / sec [5] 3.00-4.00 sec 1.09 GBytes 9.40 Gbits / sec [5] 4.00-5.00 sec 1.08 GBytes 9.32 Gbits / sec [5] 5.00-6.00 sec 1.10 GBytes 9.41 Gbits / sec [5] 6.00-7.00 sec 1.10 GBytes 9.42 Gbits / sec [5] 7.00-8.00 sec 1.09 GBytes 9.40 Gbits / sec [5] 8.00-9.00 sec 1.09 GBytes 9.40 Gbits / sec [5] 9.00-10.00 sec 1.09 GBytes 9.40 Gbits / sec [5] 10.00-10.00 sec 636 KBytes 8.66 Gbits / sec * * * [ID] Interval Transfer Bitrate [5] 0.00-10.00 sec 10.6 GBytes 9.11 Gbits / sec receiver IPS is enabled, but only on the RED0 device. I made another machine with a clean ipfire installation and tested the network cards, cables, sfp + modules and the speeds were good there, they brought what was expected. The machine called wrouter, on the other hand, is slow.

> [@whaskes](#): > > IPS is enabled, but only on the RED0 device. If you disable IPS and leave everything else untouched, does it go up to 1 Gbits/sec? I am thinking that IPS could increase the CPU load and introduce a bottleneck there, regardless if it is analyzing the traffic of the green network or not. Also, is [QoS](https://wiki.ipfire.org/configuration/services/qos) active? ---

I am thinking that IPS could increase the CPU load and introduce a bottleneck there, regardless if it is analyzing the traffic of the green network or not. Also, is [QoS](https://wiki.ipfire.org/configuration/services/qos) active? Qos is active, I have already tried to turn off both completely separately and together, but nothing has changed How can I see what can slow down my internal network? ---

> [@whaskes](#): > > How can I see what can slow down my internal network? Can you try to measure the CPU activity for all cores when you max out the bandwidth? I still think that for some reason you have a CPU bottleneck. Is it possible that you switch off the two services but for some reason either processes is/are still using CPU cycles? ---

i will test the system again this week and check it out. ---

When I measure with iperf3, only one CPU core works, sometimes it switches to another, here is an image from the top. Where can I tell this to better distribute tasks between CPU cores? Looking for software or bios? ```auto [root@wrouter ~]# top top - 13:06:26 up 56 min, 2 users, load average: 0.70, 0.66, 0.77 Tasks: 349 total, 2 running, 347 sleeping, 0 stopped, 0 zombie %Cpu0 : 0.0/0.0 0[] %Cpu1 : 0.0/18.6 19[|||||||||||||||||||] %Cpu2 : 0.0/0.0 0[] %Cpu3 : 0.7/0.7 1[||] %Cpu4 : 0.0/0.0 0[] %Cpu5 : 0.0/0.7 1[|] %Cpu6 : 0.0/0.0 0[] %Cpu7 : 0.0/0.0 0[] %Cpu8 : 0.0/0.0 0[] %Cpu9 : 0.0/0.0 0[] %Cpu10 : 0.6/0.6 1[||] %Cpu11 : 0.0/0.0 0[] %Cpu12 : 0.0/0.0 0[] %Cpu13 : 0.0/0.7 1[|] %Cpu14 : 0.7/99.3 100[||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||] %Cpu15 : 0.7/0.7 1[||] %Cpu16 : 0.7/1.3 2[||] %Cpu17 : 0.0/0.0 0[] %Cpu18 : 0.0/0.0 0[] %Cpu19 : 0.0/0.0 0[] %Cpu20 : 0.0/0.0 0[] %Cpu21 : 0.7/0.7 1[||] %Cpu22 : 0.0/0.0 0[] %Cpu23 : 0.7/1.3 2[||] GiB Mem : 13.6/31.3 [] GiB Swap: 0.0/1.0 [] ``` ---

The ability to use multiple cores is something defined by the bios firmware. However it is not something that can be selected from the bios. The firmware is either written to spread the load over cores or it is not. ---

The CPU bottle neck hypothesis seems to be correct. Even if you have a multicore, only one core is used maxing out the speed. Unfortunately there is nothing you can do, the firmware is responsible for distributing the workload, as @bonnietwin has said. When choosing the hardware for a firewall it is necessary to check both how the ethernet cards communicate with the CPU and if the CPU handles properly the multithread system. There are several discussion about this topic in IPFire forums. Personally, I decided that my next machine will be one that has been tested for a firewall job by people that know what they are doing. In the IPFire case, [a lightning wire lab appliance](https://www.lightningwirelabs.com/products/ipfire/appliances) ---

I tried the dell r720 with a debian live system. Iperf3 ran perfectly well, showed good bandwidth, 10 gigabytes, and the CPU worked well. If I boot the system with ipfirel, it will only run around 5 giga. I think the hardware problem is ruled out. Any ideas? ---

It’s not only the firmware/bios. This need only to activate the cores and a few CPU options. Multitasking over more then one core is a combination of three things: - Bios with correct options - Program logic parallelization with different tasks - OS which spreads the different tasks to different cores. This can only work if the OS knows the processor. If the firewall process use only one task, it can only run on one core… And I found one interesting point… IPFire don’t know my AMD processor completely, the CPU frequency Graph variable cpu9A0 is unknown… ---

I guess the Debian system is using features like hardware offloading and the like. Thus part of the heavy lifting is happening outside the cpu. I’ve read somewhere - I think on the suricata website - that hardware offloading would mess with the packet order so ips systems get problems when tracking connections and recommend to disable such features. I do however have a problem imagining that your processor can’t handle 10g on its own. While you haven’t said what chip you have the impressive number of cores hints at some better chipset. Do you have error messages regarding drivers for your network card (s) in ipfire? ---

There are no error messages about anything in the log. My machine is a Dell PowerEdge R720-8BAY-LFF-CTO with 2 Xeon E5-2630Lv2 cpu My previous machine had a Kontron KTQM87 / mITX motherboard running an Intel I7 4860eq processor. There was no problem with that in IPFire. Utilized 4 cores / 8 threads with a 10g connection, iperf3 showed good speeds. Suricata is disabled, only enabled on the RED0 network card.

Honestly, I‘m at a loss here. The specs of your machine should be enough even if it would only utilize 1 core I‘d say. I had the same opinion @cfusco had. But now I‘m not sure if there isn‘t another problem. Sorry, I don‘t know enough to diagnose that further.
