I assume you've ruled out possible speed/duplex issue?  What the CPU look
like while doing a speedtest?

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,

Thank you,
