Okay, This seems to work really well.

226 33.268 seconds (measured here), 5.03 Mbytes per second
175560916 bytes received in 33.27 secs (5153.0 kB/s)

The daemon used for logging never came above a top CPU usage of 1.8% at this 
throughput, and this value only got that high when my program was updating 
the mysql databases. Really the thing eating most of the CPU was the reading 
from disk and the ftp program. Here is the CPU in use for this little 
experiment:

model name      : Intel(R) Pentium(R) 4 CPU 2.66GHz

Anyways, I'll be working on doing a small release package, for those who are 
interested in this thing. Don't expect too much from it, I hardly sat a week 
at this system. It was my goal to just have a convenient way of getting 
traffic statistics for my root server and be warned if I go over the traffic 
limit I have, not add as many nifty features as possible. You can do that 
yourself if you find my package worth of your precious attention and really 
want to ;)
