we are an internet provider and use a Cisco Pix 535 failover pair in one of our server farms. The pix version is 6.3(5). Our big problem is that, when we add or modify lines on the turbo access-list, the cpu goes between 90-95% for about 5-10 minutes, causing big connectvity problems to our customers.Our pix has 1024 bytes of Ram.
Could you please give us some hints to reduce this high cpu load? On normal utilization, the cpu is about 25-30%!!
