Hi,
We have an active-active pair of cisco ASA5580-20 with software version 8.4(1)9.
There are 8 contexts on it (including admin and system). 1 context is active on Primary node and other 7 are active on Secondary node.
User traffic is going through this 1 context (2 interfaces - inside to users, outside to internet) and there are peaks to 1.16M concurrent connections, max bandwidth is 1.25Gbps. CPU usage for this context in peak hours is 63%, but we noticed that when we run "show cpu usage context all" from system it shows that system context is using 25% of CPU and "Total CPU utilization" (form output of show cpu detailed - on system context) is 88% which is bad.
In non peak hours - user context use 33.6% CPU, system use 14.5%, total CPU usage is 50.5%
So, is it normal this cpu utilization on system context (system on Primary node)?
BR,
Plamen
