Network speed on Debian Wheezy via Asus GigaX1024P and RealTek card
 
I am running a few Debian Wheezy machines (with RealTek RTL8111/8168B card, driver: r8169 Gigabyte Ethernet driver 2.3LK-NAPI) linked to a ASUS GigaX1024P switch. As far as I understand things I should be achieving 1000 Gb/s but I only get 100.

Any ideas? Anyone? Bueller?

Hi

Your switch isn't really Gigabit, at least if it is one of those:

http://www.newegg.com/Product/Produc...2E16833320404R

Looks like 2 of the ports are gigabit, while the rest is 100mbit only.

It's also advertising 10/100mbit only.

Yes, that seems to have been the problem - quite embarrassing!

Thanks
