iperf Done.

WoW! I could not have hoped for a better response! This is extremely interesting to me.

You are correct and I would like to say that to me it's just an interesting SINGLE data point to compare routers. Yes this would not be a good way to solely judge anything, However in this day and age we are sorely missing a real meaningful numbers based comparison of devices other then the typical "AC1900" "AX1800" marketing wank etc. Also keep in mind folks the way we are running iperf3 is only single thread, keep that in mind when looking at some of the very high numbers like ** AjkayAlan's** results!

Who is going to be the first member of this forum to break 100gbps??? I am sure there is at least a few folks here up to the task! So come on and join the fun, it should only take 30 seconds out of you're schedule to DL, install and execute!

Someone planted a trojan in iperf and push for it's distribution :thinking:

The problem just is, this measurement tells more about the CPU performance (single-threaded), than the achievable throughput over the network (what would be interesting for benchmarking a router). Case in point, wrt3200acm vs nbg6817 - very comparable CPU performance, but the wrt3200acm is much faster at routing (without NSS hardware acceleration for ipq806x).

Is it then a good metric for determining the CPU?
Not really, it's a specific -but rather trivial- load test of a single core, a bit too rough to draw real conclusions.

This is a crucial reminder to kill the server running as a daemon in the background!

By default iperf3 uses all CPU cores. There is a -A option which could restrict it to fewer cores.

The test is of course purely CPU. No networking hardware is involved at all, though packets do move realistically through the kernel network stack.

Well not sure what you mean with all CPU cores. Yes it would use any CPUs but it is single threaded so only will use a single core at a time.

My testing suggests that RAM performance is the limiting factor for this in higher-end systems. A system with DDR4-2600 is going to stomp a DDR3-1333 system irrespective of CPU.

The bigger problem still is what actual use this data provides, it neither tells you how fast the CPU is, nor what throughput it could deliver over its ethernet ports nor its radios (not even relative to other devices).

nor were equivalent devices equally quiesced.
