@vdsl I'll leave you to test things like that  ;)

Results of running Iperf3 are much better.

First set is via my 1Gbps switch and the hardwired Cat5e network cables.

Code: [Select]

Second set is via a patch cable between the two PC's

Code: [Select]

Last set is via a short patch cable to link the ports on the patch panel - so roughly 25 meters of cat5e

Code: [Select]

iperf Done.

Overall a lot better than yesterdays basic test, but ultimately it will be read/write speeds of my server that will be the limiting factor.

Almost forgot, attached a screenshot of Task Manager showing 1159.4Mbps whilst running Iperf3 at 10Gbps but shouldn't it be MB/s ? Definitely something not right there, if I run Iperf3 across the 1Gbps network Task Manager reports just under 900Mbps  ???

Nice, good to see that the TCP throughput is much closer to 10 Gbps! :)

Did you try iperf3 with additional streams (e.g. -P 2, -P 5)? Would be interesting to see if it can be pushed closer to the theoretical max or if you're hitting cable / card limits.

Not sure what's going on with Task Manager there, I'd agree it would seem to be showing the wrong unit.

@vdsl I'll leave you to test things like that  ;)

I'll report back when I manage to bag a couple of NICs for a decent price! :)

No I didn't, it's not something I'm familiar with so wasn't aware?

Can you use SFP+ cards and DAC cables?

I would have tested mine but I, umm, can't remember where I put it after taking it out of my desktop when I returned my motherboard.  :-[

Fair enough, you can use "-P" or "--parallel" from the client, e.g.

Code: [Select]
iperf3 -c <host or IP> -P 2

Note that it's case sensitive, and "-p" means something else entirely (sets the port number IIRC).

I'd try a couple of values, e.g. 2, 5, 10 and see what (if any) effect it has.

Can you use SFP+ cards and DAC cables?

Haven't been able to find an SFP+ option that comes close to the price of the Asus 10GBASE-T cards. It's still a possibility at this stage. Long term I'm planning to move the server into a different room, hoping to reuse my existing cat 6 cables. So I'd probably be looking at 10GBASE-T SFP+ modules anyway, which seem to be about £50 each and only advertise working over 30m of cat 6 (10GbE spec suggests 55m should be possible). I think 30m would be okay, but maybe cutting a little close for my longer runs (if just patching together at the panel).

Definitely try UDP mode, as I said earlier.

For UDP mode, use:

Code: [Select]
iperf3 -c <host or IP> -u -b 10G

(-u is UDP, -b is the bandwidth limit, which for UDP, defaults to 1 Mbps)

If you don't mind going second hand then there a quite a few options for SFP+, I missed out on an Intel X520-SR1 for £40, which appears to be identical to an X520-DA1 because I wasn't sure if it would work with a DAC cable, but by all accounts it would. Though if you're going to be moving the server and already have CAT6 installed then that would be easier, luckily for me my server is right next to all my main networking gear. Apparently https://www.fs.com/uk/ is pretty good for cables and transceivers.

Thanks for the info on Iperf3, I'll give that a go later in the week when the other stuff has arrived.

My switch turned up today, to all intents and purposes it looks brand new, it came with new cables, new pack of ears, new instructions, and proper foam packaging, just wasn't in a Netgear box.

Need to tidy up the cabling, I bought a splitter cable for the two switches, but can't unplug the other switch to change it over at the moment or I'll get complaints.




Some quick speed tests as requested:

This one is rather slow??

The PC with 20H2 version of Windows actually reports the network speed correctly.

Just waiting on the card for the server now, Royal Mail 2nd class seems to take for ever now :-(

Is that an ONT, Ronski?

And a small NAS or Intel NUC or similar?

And Iím wondering what the brightly coloured thing on the left is.

The brightly coloured thing is  a Dyson cordless vacuum. The black object bottom centre is my UPS, on the left end of the shelf is my pfSense router (a Qotom QOTOM-Q190G4-S02 Mini PC) , other end of the shelf is the Virgin SH3 and my server below, which has a quad satellite tuner for TV recording. I still have a redundant HG612 screwed to the wall, hopefully I'll never need that again.

Finally received my SFP+ card today, it wasn't supposed to include any transceivers, I guess someone hadn't noticed the two that were plugged in to it. Both Intel units, a FTLX8571D3BCV-IT and a AFBR-703SDZ-IN2, I may just have to get a cable and see if they work.



and the card which is a Supermicro AOC-STGN-I2S Rev 1



Tomorrow I'll install it and see what happens.

I installed the card this morning and it worked without installing any drivers, but Iperf3 reported only about 2Gbps transfer speeds.

Went through some fun and games trying to update the drivers, but got there in the end, but that didn't seem to make much difference, no idea why I'm not seeing the speeds I did the other day between the two PC's with the Asus cards either.

From the X99 system to the server I get:

When I run Iperf3 in parallel it does perform better, but still not as high as it did the other day.
 
File transfers to/from the server do seem roughly 3 times faster though.

I found this guide last night for updating the firmware on the Asus cards, I've updated one, but haven't done the other yet, I'll also install the Marvell drivers later. There is also some tips for improving the through put as well, which I'll give a try later.

This thread also looks useful, lists some newer firmware and drivers https://www.overclock.net/threads/aquantia-10g-lan-firmware-update-aqc107-3-1-90.1735798/

I don't recall having any issues once flow control was enabled, but maybe this firmware actually fixes the bug that caused me to need flow control in the first place?
