Differing performance Laptop (Win10Pro) + Desktop (Win7Pro)
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, 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?)
