In the course of my testing of Snort I have averaged about 40% packet
loss. I am running Snort on Fedora. The segment I am monitoring is 100
mb and is very busy. Does anyone have any recommendations for tuning
Snort to not drop so many packets? Is there any recommendations for
hardware? The CPU is running at about 40% and the memory looks fine.

First thing you should do it's to check the rules you are
using and remove the ones that don't apply to your system
or are not useful to you. Tunning the rules will give you
a performance boost.
Second thing it's logging in binary format instead of logging
in ascii format. You can use then barnyard to generate the
logs in ascii format or log to a database. That will be another
huge performance boost.

The only people for me are the mad ones -- the ones who are mad to live,
mad to talk, mad to be saved, desirous of everything at the same time,
the ones who never yawn or say a commonplace thing, but burn, burn, burn
like fabulous yellow Roman candles.
-- Jack Kerouac, "On the Road"
