Dropped packets and possible reboot of the firewall (the latter one came
from personal experience of a pix 525).

Subject: [fw-wiz] PIX 535: High CPU, High-Latency

Has anyone discovered and a reliable source of information regarding
performance or operational parameters for Cisco PIX firewalls? That is,
acceptable limits for the various resources utilized, CPU, memory,
interface saturation, etc. Specifically, what are the impacts of high
CPU utilization on this platform? What are the implications of CPU
levels exceeding 80-90%.

Many thanks,
Matthew
