Performance again

Hi all, I would like you to take a look on this: http://www.truesec.de/Perfmon.html It is the output of the performance monitor. I'm trying to find out, which network parameters have the greatest influence on Snort's performance: 1. Many open sessions 2. Big packets 3. System load 4. Internals 5. Alert Count 6. ... and so on. Therefore I took out some lines from my perfmon.log and tried to compare different situations, in which Snort were loosing packets. My first conclusion is, that the bigger the packets are, the more packets are being dropped, while the open sessions count has almost no influence. Interessting, that Snort will handle more than 700 sessions simultaneously with no packet loss :) (I only included the lines where packet drops occured). I would like any comments on this, and if available, results from the performance monitor. The results are from Snort 2.0.5 but I'll do the same with Snort 2.1.0 soon. That may be more interessting. ;) The machine is Linux 2.4.22, PW pcap, PIII 1GHz, 512MB RAM, WD HD UDMA5.
