Als Cluster Backend werden 2 10Gbit SFP+ DAC Verbindungen benutzt. Und genau diese Verbindungen zwischen den Hosts wollte ich überprüfen und kontrollieren wieviel ich darüber. Have you ever wanted to push 10Gbit of TCP with an MTU of 1500, without touching anything outside of userland? Well the parallel switch of iperf is your best friend! With this simple switch, you can fill a 10G NIC easily with about 5 to 10 threads. Depending on OS settings, NIC and a myriad of other factors, you may or may not be able to fill your connection with a single TCP connection. In an. Testing 10G network with iperf. July 4, 2014. February 22, 2018. sysadmin Linux, network. I am testing the real bandwidth I can get with a 10G network connection. My server has an intel X540-AT2 network card with 2 10G interfaces. The server is configured to use bonding in balance-alb mode, but in this test only one interface comes into play. Per Default wird bei Ethernet die MTU von 1500 Bytes verwendet. Moderne GBit und 10 GBit Adapter erlauben jedoch den Einsatz von einer größeren MTU mit 9000 Bytes. Man spricht dann von Jumbo Frames. ifconfig eth2 mtu 9000 up Messung der Performance.

I am using the absolute default settings for iperf to attain these results. iperf -c 10.X.X.X and on the server side simply iperf -s. Using a completely different set of computers I was getting very similar results with them connected via a Gigabit link. I have also tried three different Gigabit switches of varying brands with the same results. Also have pretty much all software disabled or shut down while doing these tests. What settings do I need to use on iperf to truly test. Iperf ist im Debian und Ubuntu Repository bereits enthalten, d.h. eine Installation ist ganz einfach via apt-get install iperf möglich.

  2. Achieving line rate on a 40G or 100G test host often requires parallel streams. However, using iperf3, it isn't as simple as just adding a -P flag because each iperf3 process is single-threaded, including all streams used by that iperf process for a parallel test. This means all the parallel streams for one test use the same CPU core. If you are core limited (this is often the case for a 40G host and it's usually the case for a 100G host), adding parallel streams won't help you unless you do.
  3. I am confused to see huge difference between netcat and iperf results. I am having 10 G link connecting my server and client. I am getting around 10Gb/s for iperf but only ~280 MB/s for netcat. What can be the error ? For Iperf. Server. iperf -s Client. iperf -c 172.79.56.27 -i1 -t 10 Result

Now when I run iPerf from one system to the other I'm seeing about 1 to 1.25Gb/s. Mind you both are connect via fiber at 10Gb full. I've attach screen shots of my tests, tunables, ect. I'm not really sure what I need to do to get better than 1Gb speed. Any help is greatly appreciated 10000MBit/s = 10GBit/s; Als Grundlage dient also ein Vielfaches eines Bits. Spricht man hingegen von MB/s oder GB/s spricht man in Vielfachen eines Bytes. Da ein Byte bekanntlich aus 8 Bits besteht, muss man den Umrechnungsfaktor von 8 berücksichtigen You start with a normal StarWind guidance and we never use tools you're using to test link performance, stick with an industry standards and they are IPerf & NTtcp. After you'll get the initial numbers start playing with the parameters: Jumbo frames, RDMA offload (we use iSER for our backbone traffic so no TCP is actually used, BUT you need to make sure TCP is still in the full power) etc. Only after you'll get close-to-wire speed with these tools and parameters you can start. hast du mit Iperf und dergleichen schon mal gemessen?

Am gleichen Switch (T1700G-28TQ) hängt auch der Server mit 2x10 Gbit/s. Der Rechner ist nur für Testzwecke. Iperf appears to use different TCP window sizes depending on the version and OS of the build. The actual implementation of the TCP window for a given OS is beyond the scope of this article, however, it is possible to give Iperf hints about what window size to use/request. I say 'use/request' because it it is not clear to me how one verifies the tcp window size actually in use. In the following.

Eventually the iperf will report more throughput than the netperf, and netpert will report more traffic than FTP since the latter is single threaded. In addition, iperf has the advantage of being able to define several processes at parallel, therefore the throughput is going to be greater. For this reason, I'll be using iperf to run the tests.

Most likely the Zyxel tests which you found to be inflated vs real-world usage were made using large packets, not small (e.g. 1500 byte packets vs 64-byte UDP) The switch also recognizes the link as 10 Gbit. I ran iperf tests from 12 different machines (2 times x 6). Every single connection is 1 Gbit, except the server one. So, I expect to see around 6 Gbit total (6 machines x 1 Gbit each).

On SMB 2.0 capable boxes- 2008/win7 I get about 520MB/s until the buffer copying from a 10G netapp to a client, then the client can't write fast enough to keep up. There is some serious complexity.

The 10 Gbps switch is the Hyper-V switch. That's the switch that all the guests connect to. If that switch is assigned to a 1 Gbps physical adapter, then that adapter effectively represents the uplink that allows Hyper-V's switch to communicate with a physical switch. All the guests share this single path for communication 2. Intel 10Gbit/s network cards. a)PCI-X 133 MHz bus recommended (8.5 Gbit/s theoretical limit) b)Processor (and motherboard) with 533 MHz front-side bus c)PCI slot configured as bus master (improved stability) d)The Intel 10 Gbit/s card should be alone on its bus segment for optimal performance

It appears if you have Linux available with 10Gb interfaces you can install iperf on a receiver and sender device. This is the only way I've ever successfully tested throughput for wireless in the past although obviously not at this speed. 0 Helpful Reply. Post Reply Latest Contents .

Re:Lenovo SR-Series 10Gbit FC LOM bonding capabilities and maximum speed per adapter. Even though the ethtool says it is 20gb typically it is very difficult to reach that speed. This is also true with a single port.

I then ran iperf and saw our bandwidth was around 11.3 Gigabits/s. Iperf output of two interfaces bonded without any network tuning. I was puzzled by this since I was expecting a number closer to 20 Gigabits/s, so I spent some time trying to tune our network. Some reading told me that the default TCP windows sizes resulted in poor performance when using the much newer 10GbE infrastructure so I. Bei Cat 6a bedeutet dies konkret, dass ab diesem Standard die für 10 Gbit/s Kuper-Ethernet nötige höchste benutzte Frequenz auf der maximalen Länge von 100 m unterstützt wird. Bei Cat 6 gilt dies nur bis 55 Meter, wenn ich mich richtig erinnere. Cat 7 Kabel mit RJ45-Stecker gibt es nicht, da die Pins zu nah beieinander sind, um die Grenzfrequenz störungsfrei über die Stecker-Kontakte. Running iperf between the two hosts (1 rusty PowerMac G5, 1 Intel cheese grater Mac Pro) over the management VLAN (without the ping-pong chain) gave about 940 MBit/s. With the ping-pong traffic amplifier, we got 800-930 MBit/s TCP throughput. Considering that the ping-pong traffic includes both the sent TCP data packets and the respective acknowledgements, the experiments could be concluded.

Probleme mit 10Gbit Netzwerk und 10GBit Switch

  1. Iperf 10gbe. High-performance, agile, and scalable 10/40GbE data center switches. 00-1. I am constantly getting speeds of 5 Gbits/second. C:\iperf>iperf. Note: iPerf vesions are not compatible with each other. iperf does not seems to work (connection refused), but iperf3 does and gives 4-4. 0 KByte (default) ----- Also you can tell the client to connect to your desired server port and also.
  2. Du brauchst zwei PCs, dann kannst du mit Iperf einen Benchmark machen. Eine Netzwerkkarte ist natürlich besser als Onboard, bei einer Gigabitverkabelung schaffen Onboardkarten meist 300-600mbit/s eine gute Netzwerkkarte etwa 950. Für die Netzwerktechnik sind hauptsächlich Cat5 und Cat6 relevant. Bei Cat5 kann ein Gigabit/s übertragen werden bei Cat6 10Gbit/s (allerdings mit anderem Stecker.
  3. I'm not a heavy bandwidth user I just want faster transit speeds when I need them. IMO, for the pricing the 10gbit port seems like a steal if I'm able to consistently get 2500+Mbit (big tbd though as I haven't tested but seems like it delivers > gbit speeds per the speed tests)
  4. Yes, it's been out a while. However, now that there are a few fairly mature 10Gbit ethernet NICs and switches we in the trenches need to know the real-deal, non-marketing skinny.
