ehtool show I have 1000Mb speed connection but network light on the switch is orange (not green).

Is the switch a reliable 1Gb switch? I've owned a couple of cheap switches
that said they
were 1Gb but didn't always work.

I'm using TRENDnet 24-Port Gigabit Switch

I had problem with slow connection to this PC using other switches, always slow especially trying to initiate X2go session with this PC, it take about 25sec to start session,
Trying to open X2go session with other PC on same network it take about 4sec.

But I think I'm not only the one having problem with this Intel adapter and igb driver.

Well, I don't think the driver itself is the problem. I have an AMD-based
motherboard but it
reports the same Intel device.

I have no problems getting about 850-900Mb sustained throughput. I'm using
Kubuntu, not Gentoo, but Ubuntu-based like the link you provided. My switch
is just a cheap Netgear thing. I get green lights on the switch but on the
back of my
PC I have solid green on the right and flashing orange on the left. I've
never
bothered to determine why those are the light colors. However just using
throughput testing to another local machine (see the instructions I gave
Dale
sometime ago on this list) I get good throughput.

I do not currently use the 2.5Gb interface.

Don't think I can help beyond this info.

Good luck,
Mark

Is the cable known good? I've had both poor quality manufactured
cables and also shoddily made DIY[1] cables fail to link at gigabit
speeds.

Consider the OSI layers: start with layer 1 and work up from there. Or
down, depending on your orientation. I don't judge.

1: I still make my own cables but I am much more reliable at it these
days. Experience and mistakes are great teachers.

I use different cable and not the light on the switch is green so 1Gb connection.

But the X2Go connection did not change still about 25sec. wait time for screen to appear.
It might have to do something with AMD CPU build in graphics.
