Once upon a time David Carmean shaped the electrons to say...

No way to tell. 46 long rules, or short? And there isn't a way to know
how it will be packed into FLASH. However large the filters are as a file
on a UNIX host is how large it is cached in RAM though.

>to an inteface, so that it uses up more RAM, or does it get used in

No, it isn't copied. One copy is cached, when it is used pointers point to
the cached copy.

>the same time (e.g. for POP3, DNS, and SMTP access only)? How would

Doesn't effect memory any more than one copy. CPU - that's variable,
how complex are the rules, how much traffic is there? Obviously you have
to compare each packet to the rule set. More packets, more processor time.

Your use looks ok.
