Two questions really.
Q1. What is a safe peak for a cluster (Active/Standby) pair of ASA 5520's?
During different times of the day, I can see major peaks that push the ASA cluster into the high 80's and low 90% utilization.
Q2. To combat these peaks, I've tried lowering the logging, turning off Inspections and even clustering rules so the list of ACL's is shorter for the ASA to run through for each lookup. None of these have made a measurable impact to CPU peaks. Any idea's what else I can do to save CPU time?
