Slow Performance

[Praedor]

I have 2 sites with very slow performance across a T1 link using 1720 Cisco Routers and 1T WICs. Here are the configs for both routers. I see no issues with either (with the exception of a couple of lines) but the vendor that created this link for me is out of business so I have to troubleshoot myself. Any help would be great.

Current configuration:
!
version 12.0
service timestamps debug uptime
service timestamps log uptime
service password-encryption
!
hostname wisconRtr
!
boot system flash:c1700-ny-mz.120-7.T.bin
enable password 7 15071B180B24797
!

!
memory-size iomem 25
ip subnet-zero
no ip routing
!
ip dhcp-server 172.16.5.2

!
interface Serial0

ip unnumbered FastEthernet0
no ip directed-broadcast
no ip route-cache

End

How busy are the routers when do a show proc cpu ? You might try turning onm route cache to see if this improves performance , right now it is setup so that every single packet is hittin gthe processor instead of being fast switched .

ip route-cache on the interfaces .

I am asuming that UptonRtr is back at your corporate office, and that it connects to two remote offices. However, I see that you are bridging two different WAN links to it's ethernet interface. Why are you doing this? Is there some non-routable protocol your network uses?
