If I need to reduce memory usage in a PIX525 running 7.2(2) what would be the first services to sacrifice? The default HTTP service inspection seems to offer very little but as most of our traffic is HTTP it is probably consuming some cpu/RAM.
I have three interfaces that each have an ACL of 1000+ elements. Do these consume a lot of RAM?
When I ran 7.1.2 the memory usage was 50% usually. Now it seems to be 70%. That said I have enabled multicast on the PIX - but the traffic volumes are very low.
