high-perf config?  I'll have to do some reading on that one....

There is no '-b' in the command line.  Could it be getting from somewhere 
in the config file??

I tried to break out the data but get an error on that as well:

  --== Initializing Snort ==--
TCPDUMP file reading mode.
Reading network traffic from "/var/log/snort/0920 at ...3545..." file.
ERROR => unable to open file "/var/log/snort/0920 at ...3545..." for
readback: archaic file format
Fatal Error, Quitting..

>Also, if you want to log to ascii text file, try:
><path to snort> -b -A fast -c <path to snort.conf>

Snort wouldn't start with this .  Had to revert to <path to snort> -D -c 
<path to snort.conf>

Scratching my head.......
