I have an issue that is really causing me grief. I recentely inherited a small network. There is an existing 1.5mbps Internet connection (fa0/0) (includes MPLS as well/same provider). We added a new ISP that allows for 50mb down/5mb up. I added the new ISP to fa0/1 and modified the NAT overload statements accordingly. I alo changed the default route to ONLY use the new, faster ISP connection. Using speedguide.net, I am only able to get 6 to 10mb down, most of the time. if I plug a laptop into the cable modem then I get 37 to 50mb down. Any idea why the 2811 is so slow? How much download speed can I expect to get? Any assisstance would be very much appreciated.
I have attached the config and various show outputs (nat, sh ver, memory, etc.). the file called "latest logs" contains a "sh ip traffic, sh int switching and a sh proc cpu sorted".

Doesn't matter -- you need to call your ISP - both sides need to match speed/duplex settings. Even though you're on Auto/Auto, you should still sync at what the other side wants to see. Take a few minutes, call the ISP and specifically ask them what their side is set at - once that is ruled out, we can look at some other things.
Speed/Duplex was deffinetly the first thing that came to my mind when I saw your initial configuration. From the looks of it though, he's using a cable modem as his gateway which recieves a BIN file telling it how to configure. Everything is typically set auto but certainly doesn't hurt to call them up and make sure. Also now that your multi-homing its very well possible your tests could be coming back through your other ISP interface if its seen as a better route back to the outside world. Try shutting down your slow ISP connection and see if you get the same results. Another option is to ask the ISP if they have there own bandwidth testing server. I don't see QOS configurations on your new WAN interface but there is on the Fa1/0 interface if thats your test port your using but I'm not familiar with that aspect to tell ya if thats where the problem is.
