linux

I have this little snapgear firewall. It's a little purpose built box running a custom linux, SH4 processor @240 Mhz, 64MB of ram.

Basically how close we are to capacity is a mystery to me. I know I can run top and see the status of all the processes, but how can I see just how much of the processor is going to passing data... and how to estimate when I'm going to need to upgrade, and by tweaking iptables rules, how does that help/hurt the processor.

suggestions?

I've not done much iptables… >>> More
