[flow-tools] performance question

[Craig A. Finseth]

   flow-nfilter does not do any caching.  It does potentially use a lot of
   memory to implement fast datastructures though.

To Vanish:

What's to cache with a flow-nfilter-type program?  It reads a file
and writes a subset of the file: no flow is accessed more than once.

And, as far as caching the results of the test evaluations, in my case
(which is what started this thread), I have a hard time seeing how a 
cache would be less overhead than simply doing the test itself.
