This is what I got, I have cable modem, 3com 10mb ether card pci, 150mhz, 64meg edo, I had my mtu set at 576 when I had my modem, but now I seem work better with it at default of 1500 which if for a LAN, now would it be better to increase it.. and also and suggestions for the other thing like RWIN or NDI, TTL, etc.. I can say from a good site like mircosoft I can reach speeds up to 200kb, but I just want the optimized.
