I'm having latency issue on an Internet router that is only 2 hops away from the LAN and the host monitoring the latency. It's gigabit all the way through and no duplex or speed errors are apparent on any of the interfaces in between. The path crosses my ASA before it gets to the Internet router, and that segment appears to be the issue. I can ping across other interfaces of the ASA to DMZ segments and get less than 1ms response times, but when pinging the Internet router, I get the results below.
--- x.x.x.x ping statistics ---
207 packets transmitted, 207 packets received, 0% packet loss
round-trip min/avg/max/stddev = 1.556/107.754/674.219/162.069 ms
The firewall's int and Internet router's interfaces on this segment show full duplex with no crc or input errors. The ASA is running at 93% of its memory being used, which has pretty much always been the case since I plugged it in, and the Internet router has a somewhat high proc utilization of 60%. I'm not sure where else to look for the cause. I've attached some int stats. Does anyone have a direction I could start focusing on?
