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 chi...
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?)
All three on 9K MTU Jumbo Files
Ran RAIDar on desktop so has the LEAF adapter, not on the laptop.
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.
Desktop - disabled Leaf ADapter, no reboot
