Hi have 4 E1 FR configured on my router to the internet access.
We have about 2000 concurrent connections to internet over these links.
We have a lot of congestion on the links as show on she config:
What can I do to try to increase my performance an have a better internet access?
I really appreciate your help!
All my serial interfaces are configured as follow, I send the ACL too

1st of all u have to be realistic. what is your ratio BW/customer ??
if you cannot buy more capacity than what u have now, you can implement QOS and ensure scavenger and peer 2 peer traffic is dropped.
for example you priorities ur email, DNS service and http.
but I think ur problem is the available BW shared by so many users.

? Why on the router conf. You choose the:
ip cef load-sharing algorithm tunnel

With the snmp have you check the load-sharing between the serial interfaces (with time frame do you use to pool the interface (5 minutes or less: try 5/10 seconds)?
Are the IP traffic shared well ?
