To get ping time shorter

I have forgotten which file to amend to add this :-

auto eth1
iface eth1 inet static
address 10.10.10.11

or dose it need only this:-

hardware−irq−coalesce−rx−usecs 0

That is the
/etc/network/interfaces
file


hardware−irq−coalesce−rx−usecs 0

Is only needed if the Ethernet interface used (eth1 in this example)
supports irq coalescing. Intel Ethernet chips are the most common
devices that require this setting,

this is what I have in :- /etc/network/interfaces

auto lo
iface lo inet loopback

hardware−irq−coalesce−rx−usecs 0
.
Where do I put enp0s25 in the file

auto lo
iface lo inet loopback

auto enp0s25
iface enp0s25 inet static
address 10.10.10.11
hardware−irq−coalesce−rx−usecs 0

No need if you have configured network through GUI.

You cannot configure things like irq coalescing options via the GUI

Hardware driver settings are per device so should be in the interfaces file
under the specific device (enp0s25 in this case) you are configuring,
so no, he did not have it set properly

I now have this in the file

auto lo
iface lo inet loopback

auto enp0s25
iface enp0s25 inet static
address 10.10.10.11
hardware−irq−coalesce−rx−usecs 0

I also rebooted the pc. but not it did not bring the ping time down.
It does if I just put - sudo ethtool -C enp0s25 rx-usecs 0 -in a terminal but then it dose not save it upon reboot

It looks like the

hardware-irq-coalesce-rx-usecs 0

text is corrupted (wrong dash symbol)
