Embedded NIC problem

[Hilko]

PC is HP Pavilion Elite HPE (ok it's an old one).

To be precise: HP Pavilion Elite HPE-310nl. The datasheet says there is an integrated Gigabit Ethernet!!!!
Product number: XC763EA#ABH
Serial number: [Personal Information Removed]
As you know with an embedded/integrated NIC.
I have a 1 Gb/s internet connection.
Internet speed on this HP does not exceed 350-400 Mb/s.

Note: Absolutely no driver etc. issues
Note !! and this is important I have no speed issues what so ever because when i put my network cable in my (old) server then my internet speed is nicely ~ 950 Mb/s!
Do you have an explanation?
[Same when i put a simple PCI nic in the HP pavilion: also 350-400 Mb/s].

Open the Windows "Task Manager", and switch to its "Performance" tab.

Then access some site like www.speedtest.net

and launch the test.

Switch back to the Task Manager window.

Does your CPU show 100% busy?

What speeds are listed for your Network Adapter?

It could be that your computer is too slow to run the Speed Test at its 100% speed.

Is your network-adapter correctly set to "full-duplex", or wrongly to "half-duplex"?
