Question : Problem: Unsaturate Cisco 1700 without reboot?

My Cisco 1700, configured with Fast Ethernet LAN and Ethernet WAN, "saturates" after a week or two of continuous traffic. I base this on a speed test that normally shows about 4M/sec throughput ramps down to about 1M/sec. If I reboot the router it immediately jumps back up to 4M/sec and stays there solidly for, like I said, a week or two.

I would like to find a way to clear whatever is bogged down from the command line rather than rebooting.
Have tried:
clear access-list
clear counters
clear mem low-water-mark
etc., etc. (all possible clear commands) to no avail

Another suggestion for your outbound filter:

Instead of creating acl entries causing cpu overhead like this:
!Block P2P
deny ip any 216.35.208.0 0.0.0.255
deny ip any 206.142.53.0 0.0.0.255
deny ip any 213.248.112.0 0.0.0.255
deny ip any 209.61.186.0 0.0.0.255
deny ip any 64.49.201.0 0.0.0.255
deny ip any 64.245.58.0 0.0.0.255
deny ip any 64.245.59.0 0.0.0.255

simply add route entries like this:
ip route 216.235.208.0 255.255.255.0 null 0
ip route 206.142.53.0 255.255.255.0 null 0
ip route 213.248.112.0 255.255.255.0 null 0
etc...

Same with the morpheous and kazaa IP's. Take them out of the inbound filter and add null routes to them.
MUCH less work for the router....
