Has anyone ever deployed two T1s in a MLP bundle and experienced high
TCP delays?

 Web browsing takes over 1 minute to load pages however ping and
downloads are fast. I have adjusted the tcp adjust-mss to 1400 and
tried lower settings. This actually allowed me to access certain web
sites that were not loading before.

interface Multilink5

ip access-group outside_in in

 no ip proxy-arp

 ip inspect inspect1 out

 ip nat outside

 ip virtual-reassembly

 ip tcp adjust-mss 1400

 no cdp enable

 ppp multilink

 ppp multilink fragment disable "EXPERIMENTING WITH AND JUST ADDED WITH
NO SUCCESS"

 ppp multilink group 5

 crypto map agvpnmap

interface Serial0/2/0

 no ip address

 encapsulation ppp

 ip route-cache flow

 load-interval 30

 tx-ring-limit 26

 tx-queue-limit 26

 no fair-queue

 service-module t1 timeslots 1-24

 no cdp enable

 ppp multilink group 5

!

interface Serial0/3/0

 no ip address

 encapsulation ppp

 ip route-cache flow

 load-interval 30

 tx-ring-limit 26

 tx-queue-limit 26

 no fair-queue

 service-module t1 timeslots 1-24

 no cdp enable

 ppp multilink group 5

Thanks in advance

Curt
