Lower file transfer rate over local network on Mint compared to Win10

Post by MiZoG » Fri Jan 26, 2018 8:51 pm

Using Linux in various distributions as main OS for at least the last year and specifically Mint on my 'daily driver' for the past 8 months, I've been usually able to find all answers to my Linux-related problems without ever making a post on a forum. Still I could not find any useful clue about this specific behaviour of my main pc ethernet port.

Description of the problem: I've setup a samba share on a auxiliary PC running Ubuntu 16.04 and used as my home file server. On my main comp set as a dual boot (Mint 18.03 and Win10 Pro) transfer rate from/to my Ubuntu shared folder is consistently twice as fast on Windows (>100 MB/s which is nice!) compared to Linux Mint (~40-50 MB/s). I move a lot of large files between these two PCs...

Main comp Ethernet controller is an Intel (I219-V) on a MSI Z270 series motherboard.
Some diagnostic commands...

Code: Select all

dmesg |grep eth0
[    1.647848] e1000e 0000:00:1f.6 eth0: (PCI Express:2.5GT/s:Width x1) 4c:cc:6a:b1:57:01
[    1.647849] e1000e 0000:00:1f.6 eth0: Intel(R) PRO/1000 Network Connection
[    1.647992] e1000e 0000:00:1f.6 eth0: MAC: 12, PHY: 12, PBA No: FFFFFF-0FF
[    1.649298] e1000e 0000:00:1f.6 enp0s31f6: renamed from eth0
This renaming seemed (eth0-->enp0s31f6) a bit weird at first glance but it may be absolutely normal.

Code: Select all

ethtool enp0s31f6
Settings for enp0s31f6:
	Supported ports: [ TP ]
	Supported link modes:   10baseT/Half 10baseT/Full 
	                        100baseT/Half 100baseT/Full 
	Supported pause frame use: No
	Supports auto-negotiation: Yes
	Advertised link modes:  10baseT/Half 10baseT/Full 
	                        100baseT/Half 100baseT/Full 
	Advertised pause frame use: No
	Advertised auto-negotiation: Yes
	Speed: 1000Mb/s
	Duplex: Full
	Port: Twisted Pair
	Transceiver: internal
	Auto-negotiation: on
	MDI-X: on (auto)
Cannot get wake-on-lan settings: Operation not permitted
	Current message level: 0x00000007 (7)
			       drv probe link
Nothing suspicious here as far as I can tell

What am I missing?

Hi there,
I've been using Linux Mint for more than 6 years and the recent firware upgrades (not sure from which version of firmware but I guess since 2 from the current one) has caused the same issue you're reporting.
My wife has a Win10 computer and we're sharing a NAS device on our network through a 1 Gbit network connection everywhere (our computers, our switch, our NAS, we're using UTP Cat6 cabling..) so her pc is transferring data with the NAS about 100 MB's/second whereas my Linux Mint pc is roughly getting 30 MB's/second.
It's this issue, in some way, related to the ndiswrapper driver?
2 months ago (aprox) my Linux Mint pc was transferring data with our NAS at 80/90 MB's/second.
