Thanks, I missed the offlist thing for reasons that I either hit reply button too quickly or fell into the bit bucket and I didn't look into it. I'm using routerboard 44GV card with 4 gigabit interfaces. The test I did was over ftp/sftp to one of the boxes in the home lab. mtu is about 1492 and I'm able to get gigabit speed between the lab boxes as they are cross-hooked into two procurve gigabit switches / the ones with 8 ports/ for simulating redundancy and do not go to the alix box, but switch only. Thought of switching the routerboard 44GV to quad gigabit intel, but if I'm going to invest such amount of money, better get one more horse powered one. Unfortunately most of the embedded boxes I've seen come with realtek chipset. Yet the joy is that if you make your pick correctly you will get a PCI and plug your existing adapter/ get a new one. So seems that I will have to migrate to something more powerful if I want to have gigabit everywhere. Could you give recommendations for something in Europe/ reasonable shipping costs to EU?
I'm thinking of the following options: #1 http://www.bvm-store.com/ProductDetail.asp?fdProductId=344 #2 http://nexcom.kd85.com or something similar #3 http://www.google.co.uk/search?q=embedded+quad+gigabit&ie=utf-8&oe=utf-8&aq=t&rls=org.mozilla:en-US:official&client=firefox-a Thanks for your help and happy sailing!
