I seem to be having some slowness issues with a multilink connection between a Cisco 2821 and 2811 router. I currently have two private T1 lines connecting the two routers and joined into a Multilink connection.This should give me a 3 mbps connection between my sites. However when I try and move a file between the two sites I'm being limited to less than 300 kbps even when there is no traffic. I'm hoping that you guys can help me to figure out what the problem is. I have verified with the ISP that they are providing a Layer 2 connection only so they are not filtering the bandwidth at all.
Here is the config that I have for the interfaces on the remote 2811 router:
interface Multilink1
description P2P Multilink to WABURL
bandwidth 3080
ip address 10.10.10.3 255.255.255.254
ip route-cache flow
ppp multilink
ppp multilink fragment disable
ppp multilink group 1
interface Serial0/0/0
bandwidth 1540
no ip address
encapsulation ppp
ip route-cache flow
tx-ring-limit 26
tx-queue-limit 26
no keepalive
no fair-queue
ppp multilink
ppp multilink group 1
interface Serial0/1/0
description P2P link to WABURL-2821 se0/1/0
bandwidth 1540
no ip address
encapsulation ppp
ip route-cache flow
tx-ring-limit 26
tx-queue-limit 26
ppp multilink
ppp multilink group 1

One more thing I forgot to add. On my main router, Cisco 2821, the serial connections have the following config:
interface Multilink1
bandwidth 3080
ip address 10.10.10.2 255.255.255.254
ip route-cache flow
ppp multilink
ppp multilink group 1
ppp multilink fragment disable
interface Serial0/0/0
no ip address
encapsulation ppp
ip route-cache flow
tx-ring-limit 26
tx-queue-limit 26
no keepalive
no fair-queue
service-module t1 clock source internal
ppp multilink
ppp multilink group 1
!
interface Serial0/1/0
no ip address
encapsulation ppp
ip route-cache flow
tx-ring-limit 26
tx-queue-limit 26
service-module t1 clock source internal
ppp multilink
ppp multilink group 1
