Toshiba Dynadock U3 Screen Laggy and Poor Network Performance

[pantner]

I have installed the latest version 7.2M1 and my network performance has dropped, not improved.

I used to get ~30MB/sec and now its more like 15-20MB/sec.

Video performance is remained as bad as it was before with the 'micro stutter', especially when moving over hyperlinks in IE.

I am becoming less and less impressed with these DisplayLink devices...

I am also having gigabit ethernet speed issues. I'm using a Lenovo USB3 Dock on my Thinkpad Helix. 7.2M1, all updated software/drivers, USB3 port, etc (AFAIK). My DVI output to 1920x1200 is decent however.

It definitely feels like the gigabit ethernet on the dock is running on USB2 instead of USB3. I'm hitting about 29MB/s max, though it's usually around 23MB/s. I have a gigabit switch and fast NAS that usually lets my other computers go at 90MB/s on transfers.

The dock ethernet also drops to around 15MB/s if I'm watching a video from the local drive.

Worst of all, my CPU usage goes up past 50% just from the network transfer. It's like the ethernet adapter is passing the processing to the CPU.

I hope this was just a simple coding mistake since putting a cheap ethernet adapter chip onto a $170 USB3 dock is a very poor choice.
