The PCIe net card speed is only 220Mb.Do you know the probable reason?

Hi,
There is a Marvell PCIe net card attached with Orin.The file eth.txt (3.8 KB)
is the output of the command lspci -vvvv.
And when I test the speed, the cpu occupancy rate of the speed test process is only 5%.
Do you know the probable reason why the speed is so slow?
Thanks

What is the method/setup to measure the card speed?

Have you tried other card?

Hi,
I use iperf3 to measure the speed.
The speed of another 1G card with the start register value of 0x2310000 is 944Mb.

Hi,

Please try other card on your PCIe slot. Do not compare with the one on 0x2310000…

Also, check your ethtool result on your card…

Hi,
Does ethtool result mean execute the command sudo ethtool -i eth2?
If not, what’s the parameter of ethtool?

Is this still an issue to support? Any result can be shared? Thanks

Hi,
I used the driver which is in the kernel source instead of manufacturer provided, and the speed is OK.
Thanks
