Howto test and tune Gigabit Networking (1000M)

[androsch]

BTW: Also use a fixed MAC-addr with the leading 00:06:dc numbers and disabled ipv6 and avahidaemon, if somebody still thinks this makes really a difference!

Still no improvement and i can confirm my Fritzbox (FritzOS 6.60, also actual version) is capable to handle GbE with some other PCs i'm using.

Yes this is what i expected. That is the board you sent me a couple of months ago yes? As it worked fine for my network it is something in your network / some incompatibility.

Btw, i got myself the cheapest gigabit switch i could find on Amazon to make the numbers from above:  NETGEAR GS605-400PES (which is aroud 20EUR).

Just finished some further testing with my 2 Win10 PCs with GbE-ports:

Code:

Both connected with 1GbE ports:

One acting as server:

[SUM]   0.00-10.06  sec   792 MBytes   660 Mbits/sec                  receiver

the other acting as server:

[ ID] Interval           Transfer     Bandwidth

[SUM]   0.00-10.00  sec   680 MBytes   570 Mbits/sec                  receiver

So my GbE is not too quick, but both are connected during this test via remote desktop. One is in the basement, connected to the Fritzbox (port with 1GbE), the Fritzbox to the switch (TP-Link, about 5m cable) and then with a very long cable (about 30m) to the 3rd floor in a D-Link DIR 645 router just acting as additional wifi router for the 3rd floor. The other PC is connected with a short 3m cable to the DIR-645. So this proves (at least from my point of view) even with this long and maybe not perfect connection, there is a GbE connection capable to handle at least 570 - 660 Mbits!

Using this connection (just plugging the cable from the Fritzbox from the pc to the Pine64+, this is what we get (Pine64 as server):

Pine64 acting as client:

[SUM]   0.00-10.00  sec  40.0 MBytes  33.6 Mbits/sec                  receiver

and now?

Got similar results before even with connecting one PC and the pine directly via the FritzBox or the TP-Link switch or the DIR-645, so i can not imagine any other influence than the Pine itself!


As stated again will be very interested if someone figures out the real reason for those problems with the Pine64, but for me its just working with a fixed 100Mbs port and then its stable and reliable with about 95Mbits.

Have a nice evening all together!

BTW: Yes, its the board you tested some time ago.

Btw, i got myself the cheapest gigabit switch i could find on Amazon to make the numbers from above:  NETGEAR GS605-400PES (which is aroud 20EUR).

Have ordered this switch today and will connect my Pine64+ with this switch and all of my GbE-PCs again (each separately and without any other ports active and new cables also). Will take some time (delivery till 24th), so will come back then...

Maybe we get this sorted
