High response time for ASA

gginty · ‎03-10-2010

We receive alerts from Solarwinds whenever the a threshold is reached, for example:

Node SRU-FW1.salve.edu has an average response time of 333 msms which falls above the 200ms threshold

Is 333 msms way to high? acceptable etc.. Any points to what to look for in troubleshooting would be much appreciated

We are running 8.2(1) on a ASA5520-K8, 512 MB RAM CPU pentium Celeron 2000 MZH

Thanks

If you are pinging the ASA check its cpu while you see the slow response.

If the ASA has high cpu it could explain the issue.

300ms is high, of course it all depends how many hops are in between.

You can also do a packet capture on the ASA to look at the icmp packet timestamps to see if the ASA delays to respond or if there is something in the middle that delays it.

topo:

asa--router1--router2--router3--router4---and so on ---

ping from the asa to router1 and record the time.

ping from asa to router2 and record the time

ping from asa to route3 and record the time.

See where the time increases and get intouch with the folks who maintain that device and see what might be going on.
