[Snort-users] Snort CPU usage

I'm bumping this back up.....I'm curious to hear. Is snort still only single threaded on a CPU or have newer versions allowed it to run on more than one core?

I'm wanting to make sure I have enough machine to run my WAN and about 4 VLANs

Each would have an interface to monitor, but where I'm stuck is the rule sets...

I read online where a great determining calculation is this...
1 CPU = (1000 signatures ) * (500 megabits network traffic)

So my question would be....if each interface has its own rule set aside from the main download of rules. Does that factor in?

Does anyone have a url or program where I can calculate hardware requirements for running snort on my network?
