Super Slow iSCSI

[Donutsman]

I have a QNAP TS-453A NAS, and recently set up iSCSI on my PC. My PC has 1Gbps Ethernet connected to my router. My NAS also has 1Gbps Ethernet connected to an Ethernet switch. Currently, my setup essentially uses the router as a WiFi card, but I am getting speeds of around 10 Mbps when writing to the NAS. Would switching to Ethernet that is physically connected to the NAS

(PC—>Ethernet—>Ethernet Switch—>Ethernet—>NAS) make the write speed any better?

WIfi can be pretty slow, so try all ethernet here to see if that is the issue

Switched to Ethernet, speeds improved by only 5 Mbps, so it is not the problem. I checked my NAS and it is downloading 20Mbps, but I don't know how to fix it.

What models are your Ethernet switch and router?

 

Is every part of this equation Gigabit Ethernet?
