Message-ID: <bff5f4d7-bb85-e3fa-b8b1-76d1b8e0133a@molgen.mpg.de> (raw)
Dear Linux folks,
On a Dell Latitude E7250 with Debian sid/unstable, PowerTOP 2.14 reports
the network device uses over 1.5 Watt, which is almost ten percent of
the whole system.
1.62 W 435,9 pkts/s Device
Netzwerkschnittstelle: eno1 (e1000e)
$ lspci -nn | grep Ether
00:19.0 Ethernet controller [0200]: Intel Corporation Ethernet
Connection (3) I218-LM [8086:15a2] (rev 03)
$ uname -a
Linux ersatz 5.17.0-trunk-amd64 #1 SMP PREEMPT Debian 5.17.1-1~exp1
(2022-03-29) x86_64 GNU/Linux
From atop:
NET | eno1 0% | pcki 2421 | pcko 2194 | sp 1000 Mbps
| si 1501 Kbps | so 140 Kbps | erri 0 | erro 0 | drpo
0 |
So I receive 1.5 Mbps, and send 0.14 Mbps.
Is such high energy usage expected of the network hardware?
Kind regards,
Paul
