Processing speed of ra utilities

Hey Geoff,
   Looking at your samples, ragator() can definitely
do some bulk processing for you.  With a simple
ragator.conf such as:

 Flow  100 ip  *   *   *   *    *     200  0   0
 Model 200 ip   no no no

you can generate stats for all the source class-c nets.

 Flow  100 ip  *   *   *   *    *     200  0   0
 Model 200 ip    no no no

will get you all the dst class-c net stats, in one
pass of the data.  If you want the data sorted by
network, just pipe the output through rasort(),
and with our first example ragator.conf file, you won't
be interested in the dst addr, so give this a try:

ragator -f ragator.conf -r large-file.out -w - | \
     rasort -M saddr -s -dir -s -daddr

   All the ra* programs process argus data files
sequentially, reading each record and doing whatever
processing they are designed to perform, and yes
one performance bottle neck with the simple samples
provided in the argus-clients distribution is that
they really only do one thing for each pass
of the data.

   The ra* programs are really intended as examples
and if you want to speed things up, you should
write your own ra* program to process the data in
the most efficient way.
