I've played with the memory and never saw any performance improvements when adding additional memory above 64MB on a PIX 525. I upgraded it to 256MB even and still didn't notice any difference. My personal opinion however is that there is a small difference between 32MB and 64MB so would recommend that upgrade.

Currently I have 448MB of RAM on my pix520 firewall. I want to know how much memory is enough for this beast? Even when my CPU reaches 99% utilization, the memory utilization is about 12%. I've never recalled any instances that the memory utilization ever reach more than 30%. My question is that do I really need that much memory on a firewall? Has anyone actually seen the pix firewall using even 256MB utilization? I am runing version 6.2(2) and sometime 6.3(0) build 131 Even when I am DOSing this firewall (in a lab environment), memory never seems to go above 60MB.
