Differing performance Laptop (Win10Pro) + Desktop (Win7Pro)

[Daf1]

I'm experiencing different performance levels on my Laptop (Win 10 Pro, connected via USB3 Ethernet adapter) and Desktop (Win 7 Pro, onboard NIC - Z68X-UD5-B3 motherboard : LAN = Realtek RTL8111E chip (10/100/1000 Mbit))

ReadyNAS 104, X-RAID 5, OS 6.4.2

ReadyNAS 104, Laptop + desktop on 9K MTU

Cat 5 cable all around.

Testing via mapped network drive on both.

Network adapter settings all the same except a few that aren't on the other :

Desktop

energy efficient ethernet - enabled
green ethernet - enabled
interrupt moderation - enabled
receive buffers - 512
receive side scaling - enabled
shutdown wake-on-lan - enabled
transmit buffers - 128

Laptop

vlan id - not present
wake on link change - enabled
wake on magic packet - enabled

I don't know enough about net hardware to know what these really mean.

Have recently re-installed Windows7 on the desktop - but the desktop performance has always been similar - although via drag+drop does seem to have slowed - Windows shows 30MB rather than 40MB/s it did before.

Have swapped over the cables going to laptop to desktop + re-run - same result on the desktop.

Could it just be hardware ? I find it hard to believe since speeds are well below Gb.
Some OS difference ?
One of the above settings ?

TIA

A late update to this.

Just updated my desktop to Windows 10 (just before the free upgrade cut-off) - had a few issues post upgrade (network iffy - needed to put in IP/DNS manually) and USB3 chipset drivers - but after setting jump frames to 9K - the desktop now gets the same performance as the laptop i.e. ~50MB/s

So likely a OS/network driver type issue.

What MTU sizes are set up on the NAS and the two PCs?  (Look at the "Jumbo Packet" setting on the PCs?)

[Daf1]

All three on 9K MTU Jumbo Files

[Daf1]

Ran RAIDar on desktop so has the LEAF adapter, not on the laptop.

[StephenB]

What happens if you disable the leaf adapter on the desktop?

Also, it might be worth testing w/o jumbo frames, and see how the numbers compare.

[Daf1]

Desktop - disabled Leaf ADapter, no reboot

[StephenB]

thx - you should probably re-enable JF and the leaf adapter.

What disks are in the laptop and the desktop? 

[Daf1]

Laptop
Dell XPS 13
i7-5500U
8Gb Ram
256Gb SSD

Desktop

- self build
i7-2700k
16Gb Ram
Disks:
OS + NAS test drive : 1Tb Samsung 840 Evo SSD
Additional :
- Old 1Tb Samsung HDD 7200rpm
- 2x WD Green in RAID 1
Discs controlled by AHCI in RAID configuration - Intel RST

[StephenB]

So in both cases, NasTester was downloaded (and run) from an SSD drive?

Do you see any packet loss on the connection?  For instance, downloading logs before/after the test and looking in network_settings.log?

[Daf1]

Yup - both running off the main/OS SSD
