ragu,
I would first confirm the packets per second and load on your 7200. You
might just 'sh int x/x' and examine the stats. How about CRC or frame
errors on the circuit ? Could it be a telco problem causing retransmits ?
If that is fine I would measure RT with icmp and tcp. Some pings and
traceroutes would give you step by step stats assuming you permit them
outbound. You might also want to put a sniffer (snoop/tcpdump) on an
internal segment and sniff the tcp sessions outbound. See when the return
ACKs come back. This should start giving you some ideas.
cheers,
.truman.boyes.
